WR Danny Amendola
Rams to Patriots
The Patriots signed the oft-injured receiver in response to losing super-producer Wes Welker in free agency. They are hoping Amendola matches Welker's production, while helping the Patriots get younger.
WR Wes Welker
Patriots to Broncos
He wasted little time jumping at the opportunity to catch passes from Peyton Manning. Not many players go from one Hall of Fame-bound quarterback (Tom Brady) to another.
LB Elvis Dumervil
Broncos to Ravens
An alleged paperwork snafu made Dumervil an unrestricted free agent. The Ravens made an error-free run at Dumervil and scored an unexpected coup.
LB James Harrison
Steelers to Bengals
The long-time Steelers catalyst re-emerged in The Queen City, where he has a chance to become like royalty if he helps the Bengals unseat the Steelers and Ravens.
LB Dwight Freeney
Colts to Chargers
Another link to the Colts glory years is gone. For that, the Chargers are grateful because their defense lacked proven playmakers.
WR Anquan Boldin
Ravens to 49ers
The Ravens dumped Boldin and his hefty salary on the 49ers for a sixth-round draft pick. This move looks even more prescient for San Francisco in light of Michael Crabtree's torn Achilles.
QB Alex Smith
49ers to Chiefs
He wasn't going to play in San Francisco as long as Colin Kaepernick was healthy, so the 49ers granted him his wish to be traded. Smith counts as an upgrade for the Chiefs.
WR Mike Wallace
Steelers to Dolphins
He bolted the Steelers and took his talents to South Beach, where he is being counted upon to help the Dolphins close the gap on the Patriots.
WR Percy Harvin
Vikings to Seahawks
A game-breaking wide receiver is about the only thing the Seahawks lacked last season. Trading for Harvin has the potential to solve that problem once he returns from hip surgery.
WR Greg Jennings
Packers to Vikings
Going from catching passes from Aaron Rodgers for years to Christian Ponder figures to be quite a shock for Jennings now that he's in Minnesota.
QB Carson Palmer
Raiders to Cardinals
He wanted out of Oakland and an opportunity to play for a playoff-caliber team. Well, he succeeded on one of his goals.
CB Darrelle Revis
Jets to Buccaneers
The Jets traded their best player in response to stalled contract negotiations. The Buccaneers play the Jets in the opener, which adds a bit of drama to the transaction.
S Charles Woodson
Packers to Raiders
He returned to the Raiders for a second stint after getting spurned by teams he envisioned throwing gobs of money at his feet. This could make for a nice ending to Woodson's career.
DE Osi Umenyiora
Giants to Falcons
The Falcons needed someone to fill the void created by the departure of pass-rush specialist John Abraham. Umenyiora also knows a thing or two about what it takes to win a Super Bowl.
S Ed Reed
Ravens to Texans
He got swept up in the housecleaning by the Ravens after their Super Bowl victory. Now he's hoping he can help the Texans get over the hump, too.
