Really not a particularly fresh take.  Paxton's Wonderlic score has been well documented. I read a throw by throw analysis of the Chicago game on another site and the author pointed out that it was his mechanics that are all off -- not his ability to read defenses and move through the progressions. Surprised me a bit as well, but it was really convincing. He's not setting his feet, releasing the ball at the right height, etc.

Before you insult a Bronco's intelligence on a Bronco site, maybe learn how to spell the test you are endorsing -- and be a little more certain of their facts. Nobody is a bust before they are drafted. Paxton was unanimously regarded as a late first round pick and the third best quarterback in the class.
