You want me to have any faith in a poll or the voters that run it then when two teams have the same number of losses but one of them has beaten three teams that were ranked at the time (the other having zero such wins) and owns a head to head win THAT team needs to be ranked higher.
You discredit the poll yet use where teams are ranked at the time they were played to determine how you rank teams, which is a little strange. I think USC has proven to be pretty average, they haven't had an impressive game yet. And Maryland is proving to be as bad as most people thought they would be. We've shown we don't deserve a ranking thus far.
When I look at both teams results, who they played, how those teams have played, and the scores of the games, I think it's pretty easy to see how a voter might think OU has still been more impressive overall. It's close, if UT should be higher ok, but I don't think it's a travesty or anything.
