I can understand why the play stood as called, from a replay standpoint. But that was clearly a TD, and the official on the field got it wrong. He called him out of bounds without paying any attention to him knee being down. On the last play of the game, the Iowa defender was ALL over Roundtree, officials weren't even watching the fucking play. So I think Michigan got jobbed of a chance.
But that being said, we still needed a 2-point conversion and overtime. Personally I believe Michigan didn't deserve to win, terrible play calling all day. Obviously Robinson has never heard of scrambling.
