4.99 should be wrong. He is a solid athlete but lacks elite top end speed or acceleration. However, he is thick enough where he can absorb a little bit of contact. He is a decent enough runner that we've called a few option plays thus far - see the 1:40 mark here:

He does a good job of keeping his eyes downfield, but thinks he can make any throw and when pressured has a habit of forcing throws instead of just throwing it away or running for a short gain. Of course all this analysis is only built on two games, so the sample size isn't big enough. Against South Carolina he was much more guilty of this and should have had one or two interceptions - he seemed to clean this up against Miami.
