8. Doug Martin, Tampe Bay Buccaneers
After a Pro Bowl rookie season in 2012, Martin failed to eclipse the 500-yard mark last season after a torn labrum cut his season short. Truth be told, he wasn’t exactly wowing anyone before the injury, either. Regardless, he is the uncontested starter for the Bucs, and reportedly showed up for camp looking faster and leaner. A new shame under Lovie Smith could be just what he needs to bounce back. (Al Messerschmidt/Getty Photo)
