Chris Johnson -- RB, 2008-12

Yes, he ran for over 2,000 yards in a season. He was the only thing the Titans had, and he hit a career year. However, these things sort of balance out over the long haul. He's run for no more than 1,364 yards in any other season and his touchdown production is spotty at best. Sure, you can attribute it to the Titans' offense lacking playmakers around him, but considering how much he crows and holds out for contracts, it's fair to remember that he averages 87.2 yards per game over his career. Remind yourself of this when he starts in about being one of the best in the game.
