I don't know what to expect from Minnesota players this Saturday but I do expect Michigan players to swipe at, kick at and fall on the lower legs, knees and ankles of Ohio State players early and often.
Day needs to continually warn his players to be aware of this. Especially Cade Stover, Kyle McCord, Emeka Egbuka, Cam Martinez, Devin Brown, etc. I know very few expect Lathan Ransom to be available, but they will go after him if he does play.
Expect dirty activity.
