There are a few legitimate concerns about the Michigan football team, following its 24-13 loss to Oklahoma on Saturday.
The running game didn't produce like Michigan fans expected. Neither did the defense, or freshman quarterback Bryce Underwood.
The defense also wasn't great, although it didn't help that the offense couldn't sustain a drive. One reason for that, outside of the play-calling, which was too conservative, was the poor play of the offensive line.
Greg Crippen, the starting center for Michigan football, was graded out poorly against Oklahoma, but he said on Tuesday that he was "confident" that the offensive line would get where it needed to be.
