Why the Cal Poly Mustangs should be ranked ahead of Southern Cal

I read several things on the intertubes last night that said, "no way UT should be ranked behind OU, because they beat them on the field". While that argument has some merit, I submit to you a couple of things:
1) Against the Red Raiders, TT lost Cosby and Orapko for the game, if not longer. I would have loved the Sooners to play UT without those players;
2) Cal Poly beat San Diego State who beat Idaho who beat New Mexico State who beat Nevada who beat UNLV who beat Arizona State who beat Stanford who beat Oregon State who beat USC. So you can't rank USC ahead of Cal Poly. No disrespect intended to Cal Poly, they're one of the better teams in the Great West Conference, if not 1-AA.
