Jared Allen, Chicago Bears
Allen moves south from Minnesota to join his former division rival. The Bears defense was a mess last season, and Allen's high motor will help the team improve its pass rush and in run defense. Allen will be motivated playing opposite a championship-caliber offense.

Julius Peppers, Green Bay Packers
Speaking of NFC North division rivals crossing borders, Peppers has moved north to the Frozen Tundra to offer defensive coordinator Dom Capers a versatile tool to deploy all over the field. Peppers will pair with Clay Matthews to give the Packers a one-two punch they've been lacking since Cullen Jenkins left after the Super Bowl in 2010.

Anthony Barr, Minnesota Vikings
The Vikings have a new defensive-minded coach in Mike Zimmer, and he found his new defensive weapon in Barr during the first round of the 2014 NFL Draft. Barr might take a bit of time to adjust to the NFL, but his freakish athleticism will allow him to win plenty of battles as a rookie.
Golden Tate, Detroit Lions
The search for Calvin Johnson's sidekick has taken the Lions way too long. Tate seems primed to fill that role, as he brings sure hands to a team that led the league in drops a season ago and the ability to stretch the field both horizontally and vertically.

Jairus Byrd, New Orleans Saints
Defensive coordinator Rob Ryan now has in Byrd the type of playmaker that allows him to get more risky and creative in dialing up pressures, as Byrd has the ability and range to cover more of the field than most safeties. Look for the Saints to be bringing some heat on defense in 2014.

Kelvin Benjamin, Carolina Panthers
Currently, there are no wide receivers on the Panthers roster who have an NFL reception as a Panther. Cam Newton has long been in need of a game-breaking wide receiver, and the Panthers hope they've found that in Benjamin. His size and speed will immediately help him make music on the field with Newton.

Lovie Smith, Tampa Bay Buccaneers
The only coach to appear on this list, but Smith was the best move Tampa Bay made this offseason. He is a coach to whom players respond has quickly gone about changing the culture down in Tampa. A quick turnaround for the Bucs wouldn't be a surprise to many in the media, myself included.

Jon Asamoah, Atlanta Falcons
How do you go from seconds away from the Super Bowl to a 4-12 record? You get beat in the trenches on both sides of the ball, that's how. Jon Asamoah comes in from Kansas City to help change that mentality for the Falcons after helping pave the way for Jamaal Charles' career year.

Darren Sproles, Philadelphia Eagles
Darren Sproles plus Chip Kelly equals must-watch television. That is all.

DeSean Jackson, Washington Redskins
A fully healthy Robert Griffin III with a pass-happy coach throwing to a motivated DeSean Jackson? I like the sound of that.
James D. Smith/Associated Press
Henry Melton, Dallas Cowboys
Dallas didn't make a ton of moves this offseason, but one smart move they did make was signing Melton to a one-year "prove-it" contract. Melton was a rising star in Chicago before a torn ACL in 2013 took him off the national radar. He can't fix the Dallas defense by himself but expect him to deliver plenty of disruption from his defensive tackle position.

Dominique Rodgers-Cromartie, New York Giants
The addition of DRC in NYC gives the Giants a formidable secondary for the first time in a long time. He and Prince Amukamara will be a good counter to the dangerous pass attacks in the NFC East.

Kevin Williams, Seattle Seahawks
Like previous Super Bowl champions, the Seahawks lost more players than they gained last offseason. However, they brought in the aging but effective Williams to join their defensive line platoon and help their quest for a title defense.

Antoine Bethea, San Francisco 49ers
Bethea had been a playmaker for the Indianapolis Colts, and will now look to anchor the backend of the talented 49ers defense under the tutelage of savvy defensive coordinator Vic Fangio.

Kenny Britt, St. Louis Rams
Part of Sam Bradford's struggles in the NFL have been that he's lacked a dynamic receiving corps to get the ball too. Now, with Tavon Austin, Jared Cook and a potentially rejuvenated Kenny Britt, Bradford will be out of excuses. Britt has shown flashes in the past, and if the offseason hyperbole has some truth to it, he could be in for a big comeback campaign.
Ross D. Franklin/Associated Press
Jared Veldheer, Arizona Cardinals
The Cardinals won 10 games last season but just missed out on the playoffs. Their pass protection was abysmal at times, and when their quarterback is as mobile as a statue, that's not a good thing. Signing Veldheer immediately relieves a massive amount of pressure and puts them in position to improve their offense by a fair margin.
Mark Duncan/Associated Press
Johnny Manziel, Cleveland Browns
Yes, he isn't the official starter yet. But at some point, this kid is going to play, and when he does, he'll make plenty of plays. He also represents something fans in Cleveland have forgotten about: hope.

Ryan Shazier, Pittsburgh Steelers
The once fierce Steelers defense was exposed as a rather average, slow unit last season. One way to rectify that is by drafting the fastest linebacker in college football, which is what they did with Ryan Shazier. He'll make his presence known early in Pittsburgh.
Patrick Semansky/Associated Press
Steve Smith, Baltimore Ravens
At this point, I'd imagine the chip on Smith's shoulder is larger than his smallish 5-foot-9 frame. But I won't be the one to tell him that. He should still have plenty left in the tank to provide Joe Flacco with another good target in the passing attack.
Al Behrman/Associated Press
Jeremy Hill, Cincinnati Bengals
Giovani Bernard was electrifying for the Bengals last season. So they went ahead and drafted a thunder to Bernard's lightning in Jeremy Hill. These two young runners will keep defenses honest and open up passing lanes for Andy Dalton.
Jack Dempsey/Associated Press
DeMarcus Ware, Denver Broncos
After years of being one of the league's best defensive players on a team that constantly underperformed, Ware is now chasing a title on the coattails of Peyton Manning. But will they find success together, or continue the underperforming narrative? We'll have to wait and see.
Brandon Flowers, San Diego Chargers
Flowers went from being a rising star at the cornerback position to a joke for the Chiefs last season. That was largely because he played the majority of his snaps from the slot, where he isn't as comfortable or as effective. If the Chargers keep him on the outside, we could see a return to his Pro Bowl form.
Colin E Braley/Associated Press
Dee Ford, Kansas City Chiefs
Talk to anyone around the Chiefs facility, and it sounds as if Dee Ford is the second coming of Derrick Thomas. This much hype and a first-round pedigree sound like the makings of an impact rookie season. If not ... look out, Ford.
Rich Pedroncelli/Associated Press
Maurice Jones-Drew, Oakland Raiders
The Raiders lost Rashad Jennings in free agency, and with either Matt Schaub or Derek Carr under center, Oakland will be looking to run the ball. A lot. Pocket Hercules was still effective when healthy last season and should be a great addition for the Raiders.
Charles Krupa/Associated Press
Darrelle Revis, New England Patriots
Bill Belichick plus Darrelle Revis equals must watch television. That is all.
Mel Evans/Associated Press
Chris Johnson, New York Jets
CJ2K heads to the Big Apple, looking to prove he still is the same dynamo at running back he appeared to be during his first few years in the NFL. And he better, too, because the New York media are not as kind or forgiving as those in Tennessee.
Robert Mayer/USA Today Sports
Branden Albert, Miami Dolphins
Ryan Tannehill was the most sacked quarterback in the NFL last season. Branden Albert will fix help that.
Bill Wippert/Associated Press
Brandon Spikes, Buffalo Bills
With Kiko Alonso lost for the season to injury, a lot will be placed on Brandon Spikes' shoulders to help lead a linebacking corps that will now feature two new regular starters (himself included). He was a great starter in New England and should be able to hit the ground running in Buffalo.
Aaron M. Sprecher/NFL
Jadeveon Clowney, Houston Texans
Clowney is an athletic freak, who will be teaming with a creative coordinator in Romeo Crennel and the NFL's most disruptive defensive playmaker in J.J. Watt. There really isn't a better situation Clowney could have landed in to make an immediate impact.
John Raoux/Associated Press
Toby Gerhart, Jacksonville Jaguars
After spending four seasons waiting in the wings behind Adrian Peterson, Gerhart finally has his chance to shine. And shine he will.
Mark Zaleski/Associated Press
Dexter McCluster, Tennessee Titans
The Titans were also relatively quiet during the offseason and draft, but I like the addition of offensive Swiss Army Knife McCluster to help give Ken Whisenhunt options in the passing attack, and Jake Locker a dynamic check down receiver when under duress.
Brian Spurlock/USA Today Sports
Hakeem Nicks, Indianapolis Colts
Andrew Luck is an awesome quarterback. Reggie Wayne is an awesome but aging wide receiver. Nicks all but disappeared from the NFL last season and is looking for a career reclamation project in Indy. Can you see where this is heading? OK, let me spell it out for you: Nicks rebounds thanks to the magnificence of Luck and assumes Wayne's mantle once he hangs up the cleats.
