Entering a game with your rival as a 21-point favorite, at home, is usually a good thing.

Losing that game isn’t.

The reactions after Michigan 27-24 loss to Michigan State, and their failing to defend their home turf during Saturday’s game in Ann Arbor were quick, and harsh – specifically the criticism of Wolverines coach Jim Harbaugh, and his inability to win the big game.

Since taking the helm at Michigan, Harbaugh has had just one win combined against Ohio State and Michigan State, with a 1-5 record. He has a 29-0 record against all other teams.

On the other side, Michigan State coach Mel Tucker will be able to boast that he bested the Wolverines, in the Big House, for his first-ever Spartan win.

Twitter was reeling with reaction from Michigan fans, and none were very happy.
