Hey Man, Baylor is tough.
There's no question the Big 12 South was a monster of a division (5 teams ranked in top 25 for a good part of the year -- I think all 5 are in the top 35 of at least some computers), but Cal struggled in only 2 games: a loss to the number one team in the country that they were competitive in, and another game to a 5-6 Oregon team.
t.u. on the other hand wasn't competitive with OU in the least, should have lost to KU, struggled against Mizzou, and was down at halftime to OkSU (big) and A&M. They won both games with great second half performances, but both teams completely collapsed and didn't even put up a fight.
I can't understand how a ten point win on the road against a 6-5 team can cause anyone to drop.
