I think Tate needs to be more involved in this game more than ever... His skillset is totally different than Haskins. It will force Xichigan to play out of the comfort zone. It will help Urban create mismatches that the bucks can exploit against xich D.
Now, he needs to get some series early in the game, not just the red zone special. He will keep the Xich defense is check with his running ability. He is not bad on the passing game as well.
Tate would allow the game to slow down, allowing the defense to keep fresh as well.
One last thing, if the team does not find a way to make the playoffs, Haskins might want to sit out the bowl game to limit the risk to injury before the draft.
