BCS Poll and Computer Rankings

In an interesting twist with the computer rankings of Utah. Now I am not saying they do not deserve where they are ranked in the computers but where they are at could have national title implications. Texas currently has a 2.75 average computer ranking, Utah is at 4.75 and OU is at 5.50. Why do I mention this? If OU, Texas, and Texas Tech end up being tied in the Big 12 south, Utah being in between Texas and OU could be a deciding factor in who goes to the Big 12 Championship then on to the National Championship if they win out. Would OU wins over Texas Tech and Okie State be enough to move them past Utah and Texas? Not sure but that Utah- BYU game could have national championship implications as well if OU and Texas win out.
