You saw what he did in college but every NFL team, including the Cowboys, passed on him in the draft multiple times. If any team thought he could impact games he’d have been gone long before the sixth round. At best he’ll be a contributor, which is a success for a running back selected in the sixth round in the contemporary NFL. My eyes see the Cowboys don’t have Texas Tech and Baylor on their schedule this season. 5’ 5”, 175 lbs. will provide limited production and hopefully one or two exciting moments in a 17 game season.
