Michigan lines up in crazy 10-man I formation vs. Wisconsin

Just 15 minutes into a massive Big Ten showdown, things are already getting weird.

Jim Harbaugh is known for his brand of hard-nosed, smashmouth football at Michigan, but the formation the Wolverines showed on offense Saturday is shocking even for him.

Faced with a second-and-2 late in the first quarter against No. 8 Wisconsin, Harbaugh had Michigan line up in a 10-man I formation before splitting to a normal set and gaining the first down.

Michigan would punch it in the end zone a couple plays later.
