Here are my two cents, which I can tell the internet is clamoring for.
I'm unsure why Fitz is getting nearly all of the carries. He hasn't produced this year. He's not fast enough to get to the outside; he's not breaking tackles; he's not making guys miss. Well, people say, the OL isn't blocking as well as it was last year. I agree. However, if the yards aren't readily available it might be time to try a guy like Rawls, more of a bruiser, to just take a one yard gain and turn it into three. I get the whole lateral movement thing on the veer, but it doesn't seem like Fitz is hitting holes w/ speed or power this year. I'd like to more of Rawls. I think the production has been poor enough to warrant at least a split in the carries.
It doesn't look like the OL is as good as last year. Michigan, post Notre Dame, has kind of gone into a shell offensively. This was the first game that they used effective play action to push the ball down the field. The I-Form run on the third down early was a horrendous call. However, that happens. I was happy to see that slight change. It seemed like they really needed to push the field vertically to get those safeties out of the box. They aren't getting big plays in the running game, and they aren't scoring.
I've been a fan since the early nineties, and I mostly remember M having at least one guy who could get open. They don't seem to have anyone at WR who can consistently beat someone over the top. Granted, Denard isn't the most accurate QB, but we're not looking at Manningham, Edwards, Howard, or Alexander level separation. The WR's often seem to be pretty well covered. I miss stud WR's. I also miss stud RB's. I wish that Michigan had a better back up QB, but I saw Navarre in person at UCLA in his RS freshman season, and I remember watching Mallet against Wisconsin. Unfortunately, other than Robo Henne, it's tough to play QB well out of nowhere. In long, more excellent RB's and WR's.
