Harbaugh is super arrogant and that's what is holding Michigan back right now. He isn't going to take the next step with the type of players he recruits, especially at QB and on the OL and he won't change his offense. His OL this year is awful, they are too big and slow, the only success they ever have is running right up the middle. Their guards dont have the athleticism to attack the edges so teams can stack the box on them and with no capable QB to keep them honest, the defense has it made. I just don't see him ever adapting, he's just too arrogant and the Michigan can recruit enough players on name alone to win 8-9 games every year, maybe a couple more when he gets a nice b1g west schedule draw, so there won' be much pressure on him, especially if he can get lucky and knock of tOSU every 3-4 years.
