A bad goal tend or travel call is no big deal. Nor is it with a couple of extra fouls against your team. However a couple of extra bad foul calls on your star player is inexcusable for a ref. For that reason alone, I would hope the Big 10 would review the IO-Purdue game and get rid of at least one poor official. The only game as bad was when Maryland beat us. That game should be reviewed also and all the refs should be fired. There was no way we committed that many more fouls than Maryland. Good referees are like gold and should be rewarded and given more games to ref. However, those doing a poor job need to be fired.
A side note. Once in college, I refereed an intramural game. If I had not just been known for boxing in the Golden Gloves, these guys would have deservedly kicked the stuffings out of me - lol.
