I have a couple problems with this post. The first being with the title. You are in no way defending Pryor, you are attacking him. Secondly he's a sopohmore so he has no draft stock. Also you say his passing mechanics are horrible, Vince Young didnt have perfect or textbook mechanics, neither does Tebow. So that doesnt really matter in college football.
Another thing is Pryor didnt play that badly, Ohio State dominated the majority of the game and you should blame your defense for folding at the end of the game, or Tressel for not running out the clock at the end of the first half and giving USC the chance to kick the field goal.
So dont blame Pryor for your team choking away a game in the fourth quarter, Pryor is a good QB that can only get better.
