Any evaluation of college quarterbacks must begin with an understanding of why NFL quarterbacks are successful. Talk to any NFL coach and they will tell you it begins with how a QB throws the ball. In the NFL, you have to make difficult throws against tough defenses in critical situations. It might happen only three times a game, it might happen eight times, but it will happen. If you can't do it, you will not be a high level quarterback.
