Tressel was punked into playing him for fear that he might transfer because he is unhappy about his playing time. He never developed as a passer because he didn't want to. The AD and God knows who else made Tressel play a guy who clearly wasn't ready and thought he was still in the high school game where he was more physically and athletically talented than 95% of the field. The difference is, that is narrowed to 10-25% of the field in college unless you are a big name school playing a 1AA school, then it is substantially bigger.
I don't think he is tough enough to play receiver OR tight end. Mark my words, he is going to be the Black Matt Jones, minus the drugs...maybe.
He's got to want it. He has been given everything in his career dating back to when he was 15-16. He didn't have to work for the starting gig in Ohio State or anything. Think about it, if you can get A's and B's without ever having to study, work out, or pick up a book or film study then why do all of that hard work. Shannon Sharpe mentioned 3 D's in his Hall of Fame induction speech, Determination. Dedication. Discipline. Judging from what I have seen so far in Pryor's career he has neither.
Any team selecting him is wasting a pick. He thinks he is entitled. He thinks he has a choice. First off, he is going to resist playing anything other than QB. Not only is he going to resist, but he is going to refuse to even learn it, even if he does eventually mope off and say, "Okay, I'll go to the WR meetings." Heck, Joe Theisman started off in he NFL as a punt returner. He had to work overtime to force the coaches to put him in at QB. If he wants to be a full time NFL QB, he has to put in over time. Stay late at the team facility with the offensive coordinator, QB coach, hell, even a ball boy if he can't convince those guys to work with him. But he doesn't have the 3 D's. He may not even have one or two D's, and without those his NFL dream is a dream deferred drying up like a raisin in the sun.
