Obama renews calls for nuclear reductions

BERLIN (AP) ? Appealing for a new citizen activism in the free world, President Barack Obama renewed his call Wednesday to reduce U.S. and Russian nuclear stockpiles and to confront climate change, a danger he called "the global threat of our time."

In a wide-ranging speech that enumerated a litany of challenges facing the world, Obama said he wanted to reignite the spirit that Berlin displayed when it fought to reunite itself during the Cold War.

"Today's threats are not as stark as they were half a century ago, but the struggle for freedom and security and human dignity, that struggle goes on," Obama said at the city's historic Brandenburg Gate under a bright, hot sun. "And I come here to this city of hope because the test of our time demands the same fighting spirit that defined Berlin a half-century ago."

The president called for a one-third reduction of U.S. and Russian deployed nuclear weapons, saying it is possible to ensure American security and a strong deterrent while also limiting nuclear weapons.

Obama's address comes nearly 50 years after John F. Kennedy's famous Cold War speech in this once-divided city. Shedding his jacket and at times wiping away beads of sweat, the president stood behind a bullet-proof pane and addressed a crowd of about 4,500, reading from paper because the teleprompter wasn't working.

It was a stark contrast to the speech the president delivered in the city in 2008, when he summoned a crowd of 200,000 to embrace his vision for American leadership. Whereas that speech soared with his ambition, this time Obama came to caution his audience not to fall into self-satisfaction.

"Complacency is not the character of great nations," Obama insisted.

"Today," he said, "people often come together in places like this to remember history, not to make it. Today we face no concrete walls or barbed wire."

The speech came just one week shy of the anniversary of Kennedy's famous Cold War speech in which he denounced communism with his declaration "Ich bin ein Berliner" (I am a Berliner). Obama, clearly aware that he was in Kennedy's historic shadow, asked his audience to heed the former president's message.

"If we lift our eyes as President Kennedy calls us to do, then we'll recognize that our work is not yet done," he said. "So we are not only citizens of America or Germany, we are also citizens of the world."

Obama spoke repeatedly of seeking "peace with justice" around the world by confronting intolerance, poverty, Middle East conflicts and economic inequality.

But even before his speech, White House aides were drawing attention to his call for nuclear reductions, casting it as the centerpiece of his address.

"Peace with justice means pursuing the security of a world without nuclear weapons, no matter how distant that dream may be," Obama said.

"We can ensure the security of America and our allies and maintain a strong and credible strategic deterrent while reducing our deployed strategic nuclear weapons by up to one-third," he said.

Signaling a new effort to pick up his delayed environmental agenda, Obama also issued a call to tackle climate change, an issue he has promised to make a priority since his 2008 presidential campaign.

"Peace with justice means refusing to condemn our children to a harsher, less hospitable planet," he said.

He said the U.S. has expanded renewable energy from clean sources and is doubling automobile fuel efficiency. But he said that without more action by all countries, the world faces what he called a grim alternative of more severe storms, famine, floods, vanishing coastlines and displaced refugees.

"This is the future we must avert," he said. "This is the global threat of our time."

Among those in the audience, Doro Zinke, president of the Berlin-Brandenburg trade union federation, said she heard nothing unexpected in Obama's speech.

"I think he's really got to deliver now," she said.

But others gave him credit for just coming to Berlin, five years into his presidency.

"The most important message here was that he came to Berlin and spoke to us and the world," said Catharina Haensch, a Berliner born in the communist east of the city who now works for the Fulbright Commission. "Even If it looks like he isn't able to fulfill all of his promises, you've got to keep on hoping."

Obama said he intends to seek negotiated cuts to deployed nuclear weapons with Russia, thus steering away from any unilateral U.S. reductions. Moreover, Obama said he would work with NATO allies to seek "bold reductions" in U.S. and Russian tactical weapons in Europe. Obama could face objections among NATO countries where many strongly oppose removing U.S. nuclear weapons because they worry that the Russians have a far greater number of tactical nuclear weapons within range of their territory.

In Washington, reaction was mixed.

Rep. Adam Smith of Washington state, the top Democrat on the House Armed Services Committee, welcomed Obama's announcement, saying that reducing nuclear weapons "will improve our national security, while maintaining our nuclear triad and our ability to deter and respond to any perceived or real nuclear threat.

But Rep. Michael Turner, R-Ohio, a member of the House Armed Services Committee, accused Obama of appeasement in endorsing further reductions in nuclear weapons, saying the president "seems only concerned with winning the approval of nations like Russia, who will applaud a weakened United States."

Sen. Bob Corker of Tennessee, the top Republican on the Foreign Relations Committee, said Secretary of State John Kerry called him on Tuesday and reassured him that any further reductions in nuclear weapons would not be done unilaterally. Rather, the cuts would be part of treaty negotiations subject to a Senate vote.

Corker criticized Obama's move without additional modernization of the arsenal.

"The president's announcement without first fulfilling commitments on modernization could amount to unilateral disarmament," Corker said. "The president should follow through on full modernization of the remaining arsenal and pledges to provide extended nuclear deterrence before engaging in any additional discussions."

The president discussed non-proliferation with Russian President Vladimir Putin when they met Monday on the sidelines of the Group of 8 summit in Northern Ireland. During Obama's first term, the U.S. and Russia agreed to limit their stockpiles to 1,550 as part of the New START Treaty.

In Moscow, Russian foreign policy aide Yuri Ushakov said that plans for any further arms reduction would have to involve countries beyond Russia and the United States.

"The situation is now far from what it was in the '60s and '70s, when only the U.S.A. and the Soviet Union discussed arms reduction," Ushakov said.

Alexei Pushkov, head of the Duma's foreign affairs committee, told the Interfax news agency the president's proposals need "serious revision so that they can be seen by the Russian side as serious and not as propaganda proposals."

Obama's calls for cooperation with Moscow come at a time of tension between the U.S. and Russia, which are supporting opposite sides in Syria's civil war. Russia also remains wary of U.S. missile defense plans in Europe, despite U.S. assurances that the shield is not aimed at Moscow.

Germany's foreign minister, Guido Westerwelle, is a strong advocate of nuclear disarmament and has long called for the removal of the last U.S. nuclear weapons from German territory, a legacy of the Cold War. The Buechel Air Base in western Germany is one of a few remaining sites in Europe where they are based.

Under an agreement drawn up when they formed a coalition government in 2009, German Chancellor Angela Merkel's conservatives and Westerwelle's Free Democratic Party agreed to press NATO and Washington for the nuclear weapons to be withdrawn, but did not set any timeframe.

Nuclear stockpile numbers are closely guarded secrets in most nations that possess them, but private nuclear policy experts say no countries other than the U.S. and Russia are thought to have more than 300. The Federation of American Scientists estimates that France has about 300, China about 240, Britain about 225, and Israel, India and Pakistan roughly 100 each.

Afghan Taliban claim they killed 4 US troops

KABUL, Afghanistan (AP) ? The Taliban have claimed responsibility for an attack in Afghanistan that killed four U.S. troops just hours after the insurgent group announced it would hold talks with the Americans on finding a political solution to ending the nearly 12-year war.

Taliban spokesman Zabiullah Mujahid said on Wednesday that the militants fired two rockets into the Bagram Air Base late on Tuesday.

American officials confirmed the base had come under attack by indirect fire ? likely a mortar or rocket ? and that four U.S. troops were killed.

The attack underscores the challenges ahead after the Taliban and the U.S. announced they would hold talks in Qatar to try and negotiate a solution to the violence. President Barack Obama has cautioned this would be neither quick nor easy.

Why we?ve been obsessed with Jimmy Hoffa for 38 years

News

15 hours ago

As the latest twist in the search for the body of Jimmy Hoffa commenced in a field north of Detroit on Monday, it continued a nearly 40-year fascination with Hoffa?s disappearance.

Many remain curious as to what exactly happened to the late president of the Teamsters union despite the fact that there is a generation of people who may not exactly remember what he was famous for in the first place. Author Dan E. Moldea, who has followed the case for all of its 38 years and wrote the book ?The Hoffa Wars: The Rise and Fall of Jimmy Hoffa,? found that out first-hand during a recent lecture to a graduate school class of journalism students at George Washington University.

Feds digging in Michigan field for Hoffa's remains

?I was talking about Hoffa and organized crime, and I saw the glassy looks on all these students' faces,?? Moldea told TODAY.com. ?I said, 'Is there anyone here who doesn't know who Jimmy Hoffa is?' They all raised their hands. There wasn't a single person in this class who knew who Jimmy Hoffa was.

Jimmy Hoffa, former head of the International Brotherhood of Teamsters, makes a phone call in this undated photo.

"I said, 'Jack Nicholson played him in the movie 'Hoffa.' Robert Blake played him in ?Blood Feud.? These kids had no knowledge of it whatsoever.?

However, the curiosity of the general public remains, and for some people, he is more famous for his disappearance or for being played by Jack Nicholson than for anything he did while alive. Some know him as the man who built the Teamsters into a powerful union with a million members in the 1950s, or for his Mafia ties, or simply the guy who was rumored for years to be buried in the end zone of Giants Stadium in East Rutherford, N.J. On Monday, a team of FBI agents descended on a field in Oakland Township, Mich., after former Mafia underboss Tony Zerilli, 85, claimed Hoffa?s remains are buried there.

This is the latest search for the body of Hoffa, who vanished in Detroit on July 30, 1975 and was declared legally dead on July 30, 1982. In 2006, a farm in Milford Township, Mich., was also scoured by authorities for Hoffa?s remains. In 2004, a home in northwest Detroit was searched by a forensic team for traces of Hoffa?s blood and DNA. Neither expedition came up with anything conclusive, but the fascination with Hoffa remains strong in the age when answers to most questions are one trip to Google away.

?You have a situation where a well-known American citizen, infamous in my book, is standing on a public street in broad daylight, and he vanishes,?? Moldea said. ?That should not be allowed to happen. It happens in some countries, but it should not be allowed to happen in this country. It?s one of the great mysteries of the 20th Century.?

?I think generally people like a good mystery, and even if people don?t know a lot about the case, there?s just a real fascination and unanswered questions after so much time has elapsed,?? said Helena Katz, author of ?Cold Cases: Famous Unsolved Mysteries, Crimes and Disappearances in America,? which includes a section on Hoffa. ?We live in a society which naturally wants answers to things. I think at some point, the longer it takes to get the answer, the more intriguing it becomes.?

Carlos Osorio / AP

Members of an FBI evidence response team look over an area being cleared in Oakland Township, Mich. on Tuesday, June 18.

Zerilli was in prison when Hoffa disappeared, but was an acting Mafia boss in Detroit from 1971 until 1974 with Jack Tocco as his underboss, according to Moldea.

?No matter what conspiracy theory you embrace on this thing, the Zerilli-Tocco people had to have checked off on this murder,?? Moldea said.

Zerilli claims Hoffa was beaten, taken to a pre-dug grave in the field in Oakland Township and then covered with a slab of concrete. Zerilli?s overall account also differs in several ways from the accumulated evidence regarding Hoffa?s disappearance, according to Moldea.

?This is very problematic for a lot of people, myself included, if the body is found out there,?? Moldea said. ?The scenario that Zerilli is putting out there is basically saying, 'Forget everything you've ever heard about the Hoffa case, here's the whole new scenario.' It would be dismissing 38 years of intelligence.?

However, Moldea believes the FBI is doing the right thing by investigating Zerilli?s claims.

?How can you ignore what the former boss of the Detroit Mafia is saying??? Moldea said. ?The FBI, I think has done a good job of pursuing legitimate leads. With regard to the cost, I couldn't care less. This murder has to be solved.

?If the FBI is taking this seriously, I'm taking it seriously. I?m working on a book now and about 20 percent of it is about the Hoffa case. If they end up finding a body here, I?m going to have to rewrite the ending, that?s for sure.?

Chrysler agrees to recall of Jeeps at risk of fire

DETROIT (AP) ? After initially defying federal regulators, Chrysler abruptly agreed Tuesday to recall some older-model Jeeps with fuel tanks that could rupture and cause fires in rear-end collisions.

But the recall, which came in an 11th-hour deal between the automaker and the National Highway Traffic Safety Administration, covers only 1.56 million of the 2.7 million Jeeps that the government wanted repaired. The rest are part of a "customer service action" and many may not get fixed.

By giving in to government pressure, Chrysler sidesteps a showdown with NHTSA that could have led to public hearings with witnesses providing details of deadly crashes. The dispute could have landed in court and hurt Chrysler's image and its finances.

The deal still leaves some Jeep owners with gas tanks that NHTSA just two weeks ago said were risky. Chrysler maintains that they are safe and need no repairs.

Earlier this month, the automaker publicly refused the government's request to recall Jeep Grand Cherokees from model years 1993 through 2004 and Jeep Libertys from 2002 through 2007.

NHTSA, the U.S. agency that monitors vehicle safety, contends that the Jeep gas tanks can rupture if hit from the rear, spilling gas and causing a fire. NHTSA said a three-year investigation showed that 51 people had died in fiery crashes in Jeeps with gas tanks positioned behind the rear axle.

Chrysler had until Tuesday to formally respond to NHTSA, but the deal made the response unnecessary.

Here's how the recall will work, according to Chrysler:

? The company will recall 1.56 million Libertys from 2002 through 2007 and Grand Cherokees from 1993 through 1998. If they don't have factory or Chrysler "Mopar" trailer hitches, dealers will install them. The heavy metal hitches bolt to the frame and help bolster protection for the gas tank.

? About 1.2 million Grand Cherokees from the 1999 to 2004 model years will be part of the "customer service action." Owners will get notices saying their vehicles are fine if they have factory or Chrysler trailer hitches. Dealers will inspect other trailer hitches to make sure they're secure. But if the Jeeps don't have trailer hitches, Chrysler won't do anything, maintaining that the Jeeps are safe and do not need any changes. A Chrysler spokesman was not sure how many of the SUVs are without trailer hitches.

In a letter to Chrysler dated June 3, NHTSA's Office of Defects Investigation told the company that all of the Jeeps should be recalled. "The defects present an unreasonable risk to motor vehicles," the letter said, "because people ... have burned to death in rear impact crashes."

A NHTSA spokeswoman said Tuesday evening that she was checking into details of the recall.

Chrysler Group LLC, which is majority owned by Fiat SpA of Italy, wouldn't say how much the hitches would cost, although they sell for about $200 each on websites.

Erik Gordon, a law and marketing professor at the University of Michigan, said Chrysler realized it was headed for a public-relations disaster and decided to reverse course.

"What happened is they get surprised by how loud the hue and cry is," Gordon said.

Chrysler's image will still get dinged a little "because it looks as if they have done the right thing only because they were forced to," he said.

Chrysler executives probably realized that their chance for success was slim because courts have given wide latitude to government regulatory agencies, said David Kelly, former acting NHTSA administrator under President George W. Bush.

"They have some very smart people at Chrysler and probably looked into a crystal ball and didn't think this would end the way they wanted it to," Kelly said.

NHTSA said in a statement that it's pleased with Chrysler's decision. The agency plans to keep investigating the issue as it reviews recall documentation from Chrysler.

NHTSA began investigating the Jeeps at the request of the Center for Auto Safety, a Washington, D.C., advocacy group. Clarence Ditlow, the center's director, said the trailer hitch remedy should be tested by NHTSA before the repairs are made. He's cautiously optimistic that the solution will make the Jeeps safer.

"We're no longer arguing over whether Chrysler is going to do a recall, but we're now discussing what we're going to do," he said.

Ditlow urged Chrysler to add Jeep Cherokee SUVs from 1993 through 2001 to the recall. The Cherokees are under investigation for the same problem.

Chrysler will begin notifying owners about the recall in about a month, the company said.

The last time an automaker defied a NHTSA recall request was early in 2011, when Ford refused to call back 1.2 million pickup trucks for defective air bags. Ford later agreed to the recall after NHTSA threatened to hold a rare public hearing on the issue.

In a statement on June 4, Chrysler said its review of nearly 30 years of data showed a low number of rear-impact crashes involving fire or a fuel leak in the affected Jeeps.

"The rate is similar to comparable vehicles produced and sold during the time in question," the company said. It also said NHTSA left some similar vehicles out of its investigation.

But NHTSA found at least 32 rear-impact crashes and fires in Grand Cherokees that caused 44 deaths. It also found at least five rear crashes in Libertys that caused seven deaths. The agency calculated that the older Grand Cherokees and Libertys have fatal crash rates that are about double those of similar vehicles. It compared the Jeeps with the Chevrolet S10 Blazer, Ford Explorer, Toyota 4Runner, Isuzu Rodeo, Isuzu Trooper, Mitsubishi Montero, Suzuki Sidekick and Suzuki XL-7.

Among the 51 deaths was Remington "Remi" Walden, a 4-year-old boy from Bainbridge, Ga., who was killed when a 1999 Grand Cherokee driven by his aunt was hit from behind by a pickup truck in March, 2012. The child was on his way to a tennis lesson when the SUV was struck. The fuel tank leaked, engulfing the Jeep in flames and killing the boy, according to a lawsuit filed against Chrysler by his family.

"Numerous witnesses saw Remi struggling to escape and heard him screaming for help," the lawsuit says.

The lawsuit alleges that Chrysler placed the gas tank in a "crush zone" behind the rear axle and knew the location was dangerous, and that the company failed to protect the gas tank against rupturing.

In court papers, Chrysler denied the allegations and said that the pickup truck driver's negligence was the sole cause of the boy's injuries.

Obama's Berlin speech: History raises the stakes

President Barack Obama and family, from left, daughter Sasha, first lady Michelle Obama, and daughter Malia, arrives at Tegel International Airport in Berlin, Tuesday, June 18, 2013. Obama is scheduled to meet with German Chancellor Angela Merkel, and deliver a speech at the Brandenburg Gate on European and U.S. ties. President Barack Obama is opening a 24-hour visit to Germany, the culmination of which will be a speech Wednesday at Berlin's iconic Brandenburg Gate.

(AP) ? Five years and 50 years. As President Barack Obama revisits Berlin, he can't escape those anniversaries and the inevitable comparisons to history and personal achievement.

His 26-hour whirlwind visit to the German capital caps three days of international summitry for the president and marks his return to a place where he once summoned a throng of 200,000 to share his ambitious vision for American leadership.

That was 2008, when Obama was running for president and those who supported him at home and abroad saw the young mixed-race American as a unifying and transformational figure who signified hope and change.

Five years later, Obama comes to deliver a highly anticipated speech to a country that's a bit more sober about his aspirations and the extent of his successes, yet still eager to receive his attention at a time that many here feel that Europe, and Germany in particular, are no longer U.S. priorities. A Pew Research Center poll of Germans found that while their views of the U.S. have slipped since Obama's first year in office, he has managed to retain his popularity, with 88 percent of those surveyed approving of his foreign policies.

Obama also has an arc of history to fulfill.

Fifty years ago next week, President John F. Kennedy addressed a crowd of 450,000 in that then-divided city to denounce the Soviet bloc and famously declare "Ich bin ein Berliner," German for "I am a Berliner." Since then, presidents from Ronald Reagan to Bill Clinton have used Berlin speeches to articulate broad themes about freedom and international alliances.

Obama, fresh from a two-day summit of the Group of Eight industrial economies, will speak at the Brandenburg Gate, a symbol of Germany's division and later reunification. It is a venue that German Chancellor Angela Merkel denied him in 2008, saying only sitting presidents were granted such an honor.

The past context ? and the weight of it ? are not lost on the White House.

"This is a place where U.S. presidents have gone to talk about the role of the free world essentially," said Obama's deputy national security adviser, Ben Rhodes. "He is seeking to summon the energy and legacy of what's been done in the past and apply it to the issues that we face today."

Rhodes said Obama will make the case that even though the Berlin Wall came down 23 years ago and the threat of nuclear war has dissipated, the type of activism apparent during the Cold War needs to be applied to such current challenges as climate change, counterterrorism and the push for democratic values beyond the United States and Europe.

A senior administration official said Obama will also renew his call to reduce the world's nuclear stockpiles, including a proposed one-third reduction in U.S. and Russian arsenals. He is not expected to outline a timeline for this renewed push. The official insisted on anonymity in order to preview the issue before the president's speech.

Obama will also hold a joint news conference with Merkel.

The visit was attracting widespread attention in Germany. People waved and snapped photos as Obama sped by after his arrival and a thick cluster awaited the motorcade as it passed the Brandenburg Gate. An evening news show in Berlin devoted itself to the president's visit, highlighting "Das Biest," or "The Beast," as the president's armored limousine is called.

There have been a few small protests, including one directed against the National Security Agency's surveillance of foreign communications, where about 50 people waved placards taunting, "Yes, we scan."

Merkel has said she was surprised at the scope of the spying that was revealed and said the U.S. must clarify what information is monitored. But she also said U.S. intelligence was key to foiling a large-scale terror plot and acknowledged her country is "dependent" on cooperating with American spy services.

For Merkel, the visit presents an opportunity to bolster her domestic standing ahead of a general election in September.

The U.S. and the Germans have clashed on economic issues, with Obama pressing for Europe to prime the economy with government stimulus measures, while Merkel has insisted on pressing debt-ridden countries to stabilize their fiscal situations first.

But the two sides have found common ground on a trans-Atlantic trade pact between the European Union and the U.S. At the just-completed G-8 summit, the leaders agreed to hold the first talks next month in the U.S.

Smarter Than C3P0: Future Robots Will Work in Teams, Scientist Says

In the next few decades, teams of roving robots will take to the seas, the air and other hard-to-reach spots, communicating with one another and working to solve scientific problems, according to a Canadian scientist.

Such flotillas of smart machines could peer at coral reefs from underwater and in the air, or perhaps explore terrain that is difficult for humans to reach, said Gregory Dudek, research director of McGill University's mobile robotics laboratory in Montreal.

First, however, researchers will need to make sure the robots do not overwhelm the waiting humans with data. These robots should parse much of the information themselves and communicate the most interesting results to humans, sort of like a highlight reel from a sports game.

"It's getting a robot to go in some environment ? on the surface, under the water, on the moon, wherever ? and getting it to tell me what it sees," Dudek told the Canadian Science Writers' Association June 7 during its annual meeting.

One example, he said, could be an underwater robot that sends back the locations and types of coral that it views.

'This perception of C3PO'

Last year, Dudek took on a new responsibility: leading the new NSERC Canadian Field Robotics Network. With the federal government and industry partners providing 5 million Canadian dollars ($4.91 million) in matching contributions, robotics scientists across Canada will work together on projects to advance research in the field.

This work will culminate in an annual field test, in which robots will rove together underwater or on land, for applications ranging from monitoring oil pipelines to making real-time iceberg warnings.

At the conference, Dudek showed a video of a robot that could adjust to walking from the beach to swimming in the nearby water. He said advances in the field are making these machines smarter and faster. For instance, robots can perform multiple functions at the same time: walking, analyzing and sending back information.

The public, however, "has this perception of C3PO" from "Star Wars" when talking about robotics, so it is difficult to convey how exciting this really is to researchers, Dudek said.

Networks of robots will need to balance how often they will meet and how often they'll work, he added. Regular contact will be essential to ensuring one robot isn't doing all of the assignments. For example, if two machines are exploring the city of Montreal, and one were to stumble into a dead end, resources should be reallocated, Dudek said.

Meeting, however, could involve long-distance technologies ? the same ones as humans often use. Depending on the terrain, the robots could communicate using short-range radio, Bluetooth or even light beams. But talking shouldn't happen all the time, Dudek added.

"If we say, 'Let's meet very often,' it's not efficient, and you spend all your time in meetings," he said.

PFT: Rice ready to be Ravens' new 'Ray' leader

Mike MunchakAP

The Titans have a plan for their final minicamp of the spring, but they don?t have a script.

During their final three days of work before vacation and then training camp, the Titans are working without a scripted set of plays in practice, which head coach Mike Munchak said was more for the benefit of his assistants as his players.

?That?s as good for the coaches as anybody, to make them have to think how to try to attack each other and not be able to pre-plan everything we are doing out here,? Munchak said, via Paul Kuharsky of ESPN.com. ?Once we had everything installed, once we spent the first nine OTAs getting everything in and doing it at a teaching pace where we felt they had a good understanding, then to me this is the best thing we could do.

?You can?t tackle, this is as close as you get to playing real football, at least mentally. I just thought this would be a nice change for these couple days. Let it flow, let it happen and create some situations.?

That forced offensive coordinator Dowell Loggains and defensive coordinator Jerry Gray (unless assistant Gregg Williams was doing it) to work against each other, after establishing a rough plan for the day.

?Whatever you call, you call and the players have got to make their adjustments off of it,? Gray said before the practice started. ?So we?re really going through a bunch of game-type situations: You?re in two minute, you?re in four minute, you?re in goal line, it?s first-and-10. All they are going to do [on offense] is tell us personnel. Then we are going to treat it as a game, . . .

?Not only does it help me, it helps Dowell, it helps the head coach get a chance to see what we like to call in certain situations, and the players do too. You can script and say hey, ?I can always have the pen last and win.? You?ve got to make the call from what you are looking at, what you?re thinking, what?s that going to do to you, because that?s how the game is.?

The Titans have spent aggressively this offseason, but that only adds to the pressure on Munchak and the rest of the staff. So perhaps it?s fitting and smart that they add a little on themselves in the offseason, before the consequences are real.
