neither team looks that great IMO.
If Pryor and Tressel would just swallow their pride and admit that Pryor is not a good passer right now and let him run more ala Vince Young at Texas, Ohio State is probably a top 5 team, maybe top 2. But Pryor wants to prove right now he can throw the ball when he has no accuracy. I respect him for wanting to improve as a QB, but right now use your strengths. You are a sophomore, no need to rush your development, and no need to try and be something you aren't right now.
As for USC, they are just inexperienced in some key areas. Barkley doesn't look totally comfortable yet, and they have a lot of new starters on D.
