Opinion: Jim Harbaugh changed up Michigan again. He could be onto something.

Jim Harbaugh was talking defense. He could’ve been talking about his program. 

“We needed some changeups and we needed to show some different looks,” he said Saturday afternoon, after his Michigan Wolverines opened their season with a 47-14 win over Western Michigan. 

He’d been asked about the adjustments his new defensive coordinator, Mike Macdonald, made after the Broncos scored an early touchdown.
