Blount is a complete dumb ass. He was flapping his gums all summer about how they were going to give Boise an "ass-whuping." Well, he was held for negative rushing yardage for the game. Hout, the Boise State player, isn't blameless in this, though. He tapped Blount's shoulder and said something to Blount. You can see a Boise State coach grab his player right before Blount sucker punches him. Had Blount left it at that he may have gotten off with a four game suspension. It was everything that happened after the punch that warranted the year suspension. Punching his own teammates, lunging at the fans, and generally needing four or five people to get him to the locker room.
Blount isn't a model player, though. He was suspended over the summer because he missed team meetings and workouts. The university couldn't blame this on the heat of the moment. I really hope that the NFL teams have enough sense not to draft this idiot.
Aside...
Oregon should be suspended for the year due to those monstrosities that they call uniforms.
