how in the world does Texas come in as a "close second"? not only did kstate beat them last year, Texas has looked average at best this year. ou was a complete shock... nobody saw that one coming. and florida losing at the swamp was pretty big, too. none of the other ranked teams that lost were really any good to begin with... this year it's wide open, imo.
OU losing to CU for sure. Colorado is coming off a 2 win season and OU has basically looked flawless the first couple games.
Yeah - it depends on how you look at it. OU played on the road and lost on a last second field goal, but to a much worse team. UT lost to a better team and UT is not nearly as good as OU, but it was by 20 points at home - the biggest home loss in 10 years. But I would say OU is more of an "upset" in that if they played each game 10 times, Colorado is going to win a lot less vs. OU than KSU would against Texas.
