Michigan leads the Big Ten in rushing, averaging more than 200 yards per game, and has done it with a balanced attack.
That includes the quarterbacks.
Back Carlos Brown has 77 carries and 465 yards rushing, but Brandon Minor has 70 carries for 322 yards and five touchdowns. Quarterbacks Denard Robinson (53-287-5) and Tate Forcier (86-214) also figure in the mix.
"They're really fast, and they're really good," Purdue coach Danny Hope said of Michigan's rushing approach. "They spread you out and they get the ball to them in a hurry, and it happens fast. You'd better get there in a hurry or they'll be gone."
Hope said he recruited Forcier and Robinson, so he knows their talent level.
He doesn't agree that Forcier is more of a threat passing the ball, and Robinson is the run threat.
"We thought both of those guys were top-of-the-line passers and runners," Hope said.
So perhaps that's why he said Purdue won't defend the quarterbacks differently.
The Boilermakers have struggled a bit this season not just against the run but against teams with mobile quarterbacks -- Oregon's Jeremiah Masoli and even Northern Illinois' Chandler Harnish had some success -- so it'll be interesting to see how the defense handles two options under center who can run.
