STRENGTHS: Looks the part of an NFL running back. Sports a powerful, well-built frame that provides clear evidence of time spent in the weight-room. Fluid athlete who changes directions easily and accelerates smoothly.
Comfortable with the ball in his hands. Lowers his shoulders upon contact and runs with forward lean. Good vision. Reads blocks and shows impressive initial burst out of his cuts to separate. Physical and cognizant blocker. Showed his commitment to the team with his willingness to play whatever role asked.
WEAKNESSES: Very raw as he possesses virtually no experience as a traditional running back. Took most his carries as a read-option quarterback or after taking the pitch to the outside, therefore his ability to run between the tackles is a projection.
Impressed in his toughness as a running quarterback but this role is a far cry from what will expected of him when running inside and when in pass protection (where he was not surprisingly inconsistent at the Senior Bowl). Accelerates smoothly but tops out quickly and defenders are able to catch up. Very little experience as a receiver in this run-heavy offense. Caught a total of three passes in 2013 (for 23 yards).
COMPARES TO: Mark Ingram, New Orleans Saints - Ingram hasn't been able to wrench away the starting role in New Orleans since earning a first round pick in 2011 but his powerful, downhill running style adds a degree of toughness to an offensive that is otherwise largely finesse. McKinnon is, of course, nowhere near as pro-ready as Ingram was when leaving Alabama but he offers a similar frame and running style and could also emerge as a valuable contributor once given time to adjust to his new role.
