He is still small for a center. He got bull rushed more than a few times against larger NT's last year. He was in our backfield a lot during the Utah fiasco in the first half of the bowl game.
Seni Faounuku from Utah worked him over pretty good in the first half. He got worked by the big NT from Nebraska and from Michigan as well. Maybe at guard he won't have to take on the larger NT's one on one and can take an angle at them and use more leverage.
