Michigan State's interior d-line is going to be a difficult puzzle for true freshman center John Keenoy. It helps that he enrolled early, but going up against Heath, McDowell, Knox, LT, and possibly Calhoun in a nickel scenario is a tall order for a freshman. I like some of the other pieces they have on the o-line, and I think that Keenoy will be pretty good in a year, but I'd like some more experience at the center position if I was WMU.
