20. Chris Johnson, New York Jets
Chris Johnson is so fast that he once actually raced a cheetah on national TV. Unlike the cheetah, however, it appears that Johnson may have lost his bite. That was the suspicion when the Titans cut him loose after last season. But even if he’s not good for 2,000 yards a season, he’s still a dangerous threat, and has something left in the tank at age 28. (Elsa/Getty Photo)
