Leading up to Tuesday night’s game against top-ranked Louisville (8-0), the No. 4 Michigan men’s basketball team (7-1) had found its calling card in exactly that. Coming off wins against then-No. 6 North Carolina and No. 8 Gonzaga at the Battle 4 Atlantis Tournament in which they averaged over 75 points per game, the Wolverines’ ball-screen offense was rolling. As for what Michigan had to show for it, senior point guard Zavier Simpson — a Preseason All-Big Ten selection — entered Tuesday night leading the nation in assists. His effectiveness in both passing and finishing at the rim out of the pick-and-roll was a driving force to the Wolverines’ undefeated November. But on Tuesday night, the Cardinals made it difficult for him to do either from the start. They hedged hard on some screens and sagged off of others, leaving Simpson uncertain of what to expect. Ultimately, Michigan’s offense struggled to adapt in its 58-43 loss.
