...for two reasons.
1) It was Mike Hart who coined the 'Little Brother' moniker. The way that Sparty played on Saturday proved that they really do deserve it. Coupled with Jerel Worthy's idiotic tattoo, Sparty's unapologetically dirty play yesterday indicates that an atmosphere of resentment, bitterness, hatred, and inferiority pervades Dantonio's program. They don't just see it as a rivalry, they really do hate UofM. These are textbook little brother characteristics. They could win 10 strtaight against us, and they'll still be Little Brother because that's they way they think. In Hart's words, "If they think we think that, then yeah, we think that."
2) It was also Mike Hart who called Jim Harbaugh out as not a true Michigan Man and someone who he wishes never played at Michigan. The way Harbaugh acted toward Jim Schwartz after the 49ers' victory over the Lions proves Hart right. Harbaugh clearly has issues with sportsmanship and class. This is part of a pattern of behavior by Harbaugh dating back to his days at the University of San Diego. He carries himself like a fratboy jock, not a coach. These are not the qualities of a Michigan Man.
In conclusion: Mike Hart is a genius.
