sure McCoy was better earlier.....but at their best, McCoy wasn't in the same world as Vince Young. Sorry, watch the film. The OSU 2005 defense was perhaps our best under Tressel. We loaded up to keep VY from beating us with his legs. Instead, he beat us with his arm. VY had the best passing performance against a JT team in my opinion outside of Phillip Rivers in 2003. The difference was that Rivers posed no threat running the ball like VY did and the resources we deployed to stop each of them was totally different.
McCoy was a fantastic QB and close to being one for the ages. But for one single year....which is all that I was talking about....Vince Young was the best CFB player I've seen in person. He made some mistakes but more than made up for any of them. He challenged the rest of the team to meet him in offseason workouts at 6:30 am. He was the leader.
And as far as that USC team having issues on defense.....I've read on this site before that USC was chock full of incredible athletes on that team that when they were focused and up for a team, they were absolutely dominant. From what I saw that NC game of USC vs Texas, Vince Young was facing a USC team that was focused and fired up.
