Often injuries, in hindsight can appear to be "stupid" as it relates to how the coach was using the player.  I do not think that is the case here. A QB can get sacked, hit late after passing the ball, "nailed" after handing the ball off,  etc....many would argue a moving QB is less likely to get hurt than a stationary one. 

If this happened in the 4th quarter and Oregon holding a 35-point lead...yeah, that is stupid. 

Florida's starting QB Luke Del Rio suffered a season ending broken collarbone in a game yesterday  after "rolling out of the pocket, completing a pass and getting knocked down." So was the coach stupid for having him roll out and pass?

What I thought was stupid and inviting an injury was against Wyoming with Alie in the waning seconds  throwing a pass to the end zone versus taking a knee and getting off the field...injury to Alie, a WR, an OL...and I got ripped on here for suggesting  that thought!?! 

Trying to win the game is different than piling on.
