I like your OU team better than USC. Any of these teams are going to look mighty impressive. I realize it is all opinion and no way to prove any of it and it would be a real time waster to attempt to make a case for or against any team or player list. So, I'll still maintain that my NU team makes USC's look plain jane. This is quick off the top of my head, in no particular order. I didn't study stats or anything like that, did not count to a correct 2 deep, and I'm sure I'm missing people but I'd field this team in a heartbeat.

In their college prime, with team chemistry, no personal/crime problems (in defense of Phillips), etc.
And like I said previously, the only place I feel weak at all may be WR & LB. You will not ever come up with better combined O line or D lines and that is where it all starts.
I would challenge anyone to field a team, any team, any combination, that can beat that.
