There was a ton of problem/issues with Michigan's Football program after the Outback Bowl. I left that stadium and felt like I had just got swindled out of my money as the team that was playing was one I didn't recognize.
Changes needed to happen and they did. One of the hardest changes that needed to be made was by the head coach himself. Football coaches are hard headed, if they have been successful doing things their way, then it will work over and over. That is why it's so rare to see coaches change their philosophy or approaches even though the game around them changes.
