i think their defense is in for a rude awakening against a motivated ohio state team playing at home. no more hutch/ojabo wrecking osu tackles like last year. and lets remember, osu scored a lot of points and moved the ball fairly well on michigan. and this year they get osu refs.
otoh, michigan's running game is better than last year. i am worried about right tackle. osu has two five star dynamic first round pick defensive ends. passing downs will be a big problem for michigan.
hopefully they dont have too many of those.
