Never has been and never will be an NFL caliber drop back passer. That being said he never has been and never will be an NFL caliber runner.
What he is and was simply was a college caliber winner, a trait that is irrelevant in the NFL as many a QB like Danny Weurful and Tim Tebow.
So I ask, what in the heck did Payton see other than himself in the guy and what’s the point now in investing any more time in him.
I’d scour the waiver wires for another young QB who at least will sit in the pocket and go through his progressions before running scared out of the pocket.
