I watched him play once this year, and that was the impression I got from him - one cocky & arrogant SOB. From the attitude I saw, just the way he reacted to plays on the field and interacted with his teammates, I wouldn't want the guy on my team. Good decision by Croom not to offer him.
As far as ability, he was a very athletic QB. Not the best arm I've seen this year, but he didn't have many tools other than Thames (who by the way was a real workhorse). He was a lot more mobile than I expected.
