Perhaps I'm bias because I want bad things to happen to everybody associated with that university as a whole, but Glennon is a bust waiting to happen.
He wows you with his immense size and cannon arm. That's all good and all, except his pocket presence is meh, he doesn't move his feet well at all, he terrible throwing on the run, that's if he can even get out of the pocket without getting sacked, and he's wildly inaccurate on mid-deep throws with zero touch on the ball.
I'm sure some coach will draft him because of his tools. It's why State let Russell Wilson go... For this guy.
But they better let him develop like a mother, and that team better have a fantastic QB coach or he's nothing more than a third stringer with a strong arm.
