The blatant missed face mask call in the first half. The td call. The blatant non passing interference call on the pass to Coleman. The fumble on the last possession. The terrible spot that didn't stop the clock, not a single holding call on their Oline (I generally dont track those any more because clearly Big Ten refs have been told holding doesnt happen against Nebraska). I'm sure there are others I'm forgetting. Doesn't absolve piss poor play, but the refs were clearly calling the game for Mich St.
