The Wolverines forced four turnovers and held the Boilermakers to just 213 yards of total offense as they opened up Big Ten play with an emphatic win.
Mattison admitted that the defense is improving, and singled out linebacker Jake Ryan for special praise.
“I was pleased with the effort. There were plays in that game that I was very pleased with. You could see Jake growing last year. The thing that’s pleasing, and it would be the same of every guy on our defense, he gets hungrier every day. He’s a guy that we’re really counting on,” Mattison said at a press conference on Wednesday.
“When you looked out there, it was the way I perceived a Michigan defense, where you had all 11 players running as hard as they could to the football,” he continued.
Michigan is set to lock horns with the Illinois Fighting Illini on Saturday, and the 62-year-old warned his troops over the threat posed by quarterback Nathan Scheelhaase.
“He’s a tough guy to defend. He’s a competitor. He’s the kind of quarterback that as a defense, you better make sure you’re playing hard,” Mattison concluded.
The game is set to kick off at 3:30 EST at Michigan Stadium.
