Every NFL offseason, teams make moves to upgrade their rosters via free agency or the trade market with veteran talent. Sometimes it works better (Peyton Manning to the Denver Broncos) than others (Laurent Robinson to the Jacksonville Jaguars), but the goal is always the same: Improve the team and give the opposition another weapon to game plan against.
Of course, some require more planning than others. Let's examine the five offensive offseason additions that will make the biggest impact for their new teams this season.
Creative ability is what you get from the former Minnesota Vikings wide receiver. Pete Carroll and the Seahawks took a big risk when they made the trade to acquire Harvin and rewarded him with a new contract that paid out $25.5 million guaranteed. That's big money for a slot receiver who isn't going to consistently align outside of the numbers. However, Harvin gives the Seahawks multiple options from a play-calling and formation perspective, along with the value he brings to the return game. He's an explosive player in the open field who can produce after the catch from a variety of alignments.
