Arguably no running back taken in the 2017 draft has more to prove than Mixon. On talent alone he should have been a first-round selection, as he showed a complete package of skills at Oklahoma. The 6-1, 226-pound back has elite burst, exceptional elusiveness and the strength and bulk to thwart tacklers with stiff arms or simply lower his shoulder and grind out extra yards. He also flashed soft hands and plus route-running ability, along with a willingness to pass protect, making him a true three-down option. Overshadowing his on-field skills is a volatile off-field reputation, and a 2014 incident in which he punched a female student led to a suspension for that entire season. The Bengals drafted Mixon in the second round and have a history of taking on talented players with similar risk profiles, but as Vontaze Burfict has shown, they aren't always able to keep such players on the straight and narrow. With Jeremy Hill struggling the past two years and Giovani Bernard recovering from a torn ACL, the door is wide open for Mixon to take on a large workload for Cincinnati right away, but he'll be on a very short leash if further off-field troubles surface.
