Agreed with this post in it's entirety.
I think the main reason people felt it was such a shocker was because of, well, two things actually: Oklahoma is one of the all time powerhouses in college football. Also, because it was such a close, high-scoring and exciting game. The finish was spectacular.
But yeah, I really wasn't surprised in the least when Boise State won that. Actually, I thought they would pull off the "upset".
