A nine-year veteran and five-time Pro Bowler, Marshall fought through nagging leg injuries most of last season and finished the year on the injured reserve due to fractured ribs and a punctured lung. He produced just 721 yards receiving. Prior to last season, Marshall racked up 1,000 yards receiving in seven consecutive seasons.

While Marshall's ability has never been questioned, he has often been a distraction.
Last season, Marshall was part of a postgame locker room rant after a loss to the Miami Dolphins, and he challenged a Detroit Lions fan to a boxing match on Twitter. In addition, he had weekly television duties as an analyst on Showtime's "Inside the NFL."
