That 3rd quater Army INT on 3rd and goal at the Michigan 5 (and I guess the false start on 2nd and goal at the Michigan 1) was very costly. Not only could it have been 17-7 or 21-7 Army hallway through the 3rd quarter, but Michigan went straight down the field in 12 plays to instead tie it 14-14 at the end of the 3rd quarter.
It was also Army's 2nd pass attempt all game. Why try that then and there inside the 5?
And Army has to punt to start the 4th.
