I think they burnt his redshirt by using him on special teams. I thought I saw something where he played in all 11 games. That's one area where he can use his speed. Looking at his recruiting bio it says he was runner-up in South Carolina's 5A 100 meter finals but then says his 40 time is in the high 4.5's.
Pruitt may letting him do this for a couple of reasons, getting his quickness improved and showing recruits he'll let them run track. Fulmer never particularly liked the 2 sport thing, Dooley didn't like anything that might help the team, and Butch, well honestly, I still don't know what Butch liked.
