When Indiana has been in a position to pull off an upset, the Big Ten officiating has usually done its best to interfere. This has happened almost yearly in the past 10 years.
The Bill Lynch chewing gum game at UM is a fine example. Playing at Iowa that same year comes to mind. Two years ago against Ohio State when they mugged our WR in the endzone on the last play of the game with no call. Many, many games I could talk about..last year in East Lansing the official didn't have the sack to pull the flag on an awful holding penalty that would've probably been curtains for MSU had it been called properly.
You've got to get those calls going your way, especially when you're a big dog going into the game. The officiating in the Big Ten is lousy, has been for years.
