ANN ARBOR, Mich. — It turns out it was a smart move for Michigan football to have its biggest recruiting weekend in Week 4 against new Big Ten rival (and old Pac-12 rival) USC. Because not only did the Wolverines manage to upset the No. 11 Trojans, but the prospects in attendance got to witness an unparalleled atmosphere.

There are highs and lows every week in college football. The winners and losers for Week 4 start with Southern California's loss to Michigan.

No. 18 Michigan inflicted a pair of significant blows in the first half against No. 11 USC on Saturday, taking a 14-3 lead into the break behind stingy defense and explosiveness in its run game. Kalel Mullings busted a 53-yard touchdown run on the Wolverines' third possession to open the scoring after the teams traded early punts.
