9. Jonathan Stewart, Carolina Panthers
The Panthers’ run game can be as unique as it is because of Cam Newton, sure, but it also relies heavily on Stewart in the lead role. The eight-year veteran came within 11 yards last season of the 1,000-yard mark, which would have been his first time there since 2009. But it was more a combination of DeAngelo Williams’s presence and Stewart’s own injury issues that kept him from those levels from 2010-14, not any problems with his game. With Newton keeping teams honest on the edge, Stewart is free to blast defenders between the tackles, although he also has the wherewithal to bounce outside when the situation calls for it.
