That and the fact that that program seems to roll no matter who's behind Center were what worried me most about him. Plus, his style of play does worry you about his ability to stay on the field.
I loved everything I saw when he played and that he was doing it in a pro style offense. Loved his physical and mental makeup. All that was top notch. I liked him more than any other QB in the draft and I would have been happy to take him where the Rams were before they traded up, but I thought the concerns were legit and significant enough to not mortgage the farm for him.
