If you are unwilling to look at anything beyond money, then, yeah it was the wrong decision. I think most pros will tell you that being a college star is more fun than pro ball. The window of opportunity for Andrew Luck to be a college football star and to live with his friends and teammates is smaller than that of being a millionaire in pro ball. It is a risk to go back to school, but I'm sure it is a calculated risk. Sam Bradford's success after losing his last college season to injury makes it seem like an even smaller risk.
