When it comes to running the ball for Iowa, everything revolves around Marcus Coker. If it wasn't for Marvin McNutt, Coker would be the heart and soul of this offense.
He is one of the best young backs in the Big Ten that nobody seems to know about. He only stands six feet tall, but weighs 230 pounds. He is an absolute load to bring down.
He resembles some of the other great backs Iowa has recently boasted, such as Shonn Greene and Adam Robinson.
It will be interesting to see whether or not Michigan can slow Coker down. If they can, then it will prove that Michigan's run defense is for real. If they can't, Iowa will just keep feeding him the ball.
He is only 30 yards away from 1,000 on the year, and there's a good chance that he gets it on Saturday. If Michigan can hold him under 100 yards, that would have to be looked at as a success.
Just a true sophomore, Coker will only get better over the next two years.
