You see its simple, really. Louisville took 1 QB commitment in 2011 and that QB committed to them late December of 2010, 10 weeks before signing day. Louisville didn't think they had a shot at getting him until Randy Shannon's got canned. That QB was Teddy Bridgewater. So if their plan was to take 1 QB in the class, which it was, you obviously take the most talented prospect you can get which was obviously Bridgewater.
What part of that do you not understand?
