watching the game on replay, the offensive line obviously stands out. they dominated ohio state. and ohio state's defensive weakness at linebacker came back to haunt them. they couldnt plug holes, get off blocks, or stop haskins.
on defense michigan's tackling stood out to me. they kept ohio state's skill players in front of them and tackled them. they made ohio state take their time and go all the way down the field. not many huge plays or quick strikes.
iowa will be the complete opposite type of challenge.
