From draft analysis, he is a 5' 10" 216-pound 'plodder' type back that ran a 4.5 time in the 40. He may make a good #2 or #3 back but truth be told it would be nice to get a running back more in the mold of Pollard (a speedy back that can make catches out of the backfield) especially given Pollard is coming off a major injury and is on a 1-year franchise tag.
I really like Devon Achane. Although smaller at 5' 8" and 188 pounds, he ran a 4.32 time in the 40 and is a former track star with madden joystick moves with a constant home run threat. He is projected as a 2nd round prospect and would fit nicely in the Dallas backfield.
