ANN ARBOR, Mich. — The course of a season can change in the tiniest sliver of time — or, if you ask Western Michigan, in no time at all.One minute, Kyle Whittingham was the coach who was going to make everything right at Michigan. The next, he was the coach who was going to lose his debut to a team from the MAC. One controversial second of game clock later, Michigan fans were swarming the field to celebrate a Hail Mary that many impartial observers argued shouldn’t have happened.Michigan got very, very lucky Saturday night. By the time Bryce Underwood’s first Hail Mary attempt whistled out of bounds, well beyond the reach of any eligible receiver, everyone inside Michigan Stadium had accepted that the Wolverines were going to lose. And let’s be honest: They deserved it. At no point after its opening touchdown drive did Michigan look like the better team. There was nothing fluky about the victory Western Michigan was preparing to celebrate.Michigan’s victory, on the other hand, was shrouded in controversy. Underwood still had to throw the pass, and JJ Buchanan still had to catch it. Buchanan, the best jump-ball receiver on Michigan’s roster, made an incredible play to haul in a 47-yard prayer and give Michigan a 13-12 victory.What in the world just happened at Michigan?Austin MeekThe play only happened because officials gave Michigan an extra second. Replays on the NBC broadcast made it appear that time expired before a Western Michigan defender touched Underwood’s first Hail Mary attempt. Early Sunday, the Big Ten released footage of the officials’ replay decision that showed a second on the stadium clock when the defender touched the ball. Maybe we should call it Schrodinger’s Second, both there and not there.“When I see zeroes on the clock, I feel like we lost the game,” Underwood said. “That’s what it was. Then we had one second. The thought was, ‘Give my guys an opportunity,’ and that’s what I did.”Michigan looked lost for most of the 59 minutes and 59 seconds leading up to that final play. The Wolverines couldn’t keep their offense on the field or get their defense off of it. Underwood looked like an even shakier version of the quarterback we saw last season, despite so much talk about his offseason breakthroughs.
