All you have to do is watch the Gruden QB camp clip to understand why he fell out of the draft.
He doesn't know anything about the game. He had 0 answers to Grudens questions. And even when Gruden pointed out 3 open receivers on one of Brays interceptions Bray came back with "if I threw that same ball I need to do..." No, you just don't throw it.
To think he gave himself a 7-8 on preparation if guys like Brady are a 10. Pffffft.
