I looked at a couple of Indiana message boards after the game. As can be predicted, they blamed the officiating for their loss. They claimed the officials were obviously biased in favor of UCLA and had this bias not been there they would have won.
It never fails, for the most part, every fan believes the officials are biased against their team. Yes, the refes don't get every call right, but it goes both ways. The real issue is observational bias by the fans. I am guilty of it myself at times. It is part of caring about your team, buit some people just take it too far.
