I was far more impressed with BYU beating Tennessee on the road last week... USC and Tennessee are both programs with a lot of tradition, but both aren't great teams at the moment. There's no doubt BYU fans should be happy about the wins though. Those are two programs that have a GDP larger than many developing countries, and both programs are traditional football powers.
Actually, I can see why fans would get excited and rush the field... I was little annoyed when the officials were still reviewing the play seeing the fans jumping around on the field... but, I'm sure there was a ton of emotion in the stands, and may as well let them enjoy themselves... oh & at least church won't be so solemn/depressing tomorrow.
