15. Percy Harvin, Seattle Seahawks
After spending most of his first season with Seattle convalescing, Harvin was finally full-go just in time for the Super Bowl. That 87-yard kickoff return showed just the kind of explosive player he can be. The Seahawks are still handling him with kid gloves in training camp, but he appears to be ready to justify all of those draft picks Seattle surrendered to get him. (Ronald Martinez/Getty Photo)
