M*chigan's defensive stats are a tale of 2 teams. UM domintated bad teams defensively. They didint look so hot against teams with a pulse
Utah complete 72% of its passing attempts and rushed for 129 for a 3.5 ypc average
Against MSU they played their best game defensively against a quality opponent allowing 386 total yards while limiting MSU to a stellar 1.8 ypc A game they should have won except for a bad snap on a punt.
That said they clearly should have lost to Minnesota who SHREADED their defense to the tune of 461 total yards while allowing a 4.1 ypc average
Indiana also should have beat UM steam rolling the UM defense to the tune of 527 total yards of which 307 were rushing yards for a 5.9 ypc average
Ohio State rolled up 489 total yards of which 369 were on the ground. The buckeyes averaged 6.8 ypc while eviscerating the skunk weasels 42-13
UM had a good defense. I dont think it was an elite one though.
