It all had to do with two factors that should not have anything to do with it. As for the preseason rankings, Auburn was ranked 17th in the AP and 18th in the ESPN coaches poll. Another one of the main reasons OU was at the NC instead of Auburn was Bowling Green. Bowling Green was scheduled to play Auburn but backed out at the last minute to play OU, which left Auburn playing a division 2 school and ruining their SOS. These two reasons are not enough to keep AU out of their shot at the title. AU played better teams than USC or OU. At the time they played them, Auburn beat 3 top 10 teams, and one of those twice. OU beat two and USC beat one. Auburn was clearly the better candidate of the 3.
USC was not as good as OU made them look. I mean honestly, Cal nearly beat them. I believe Auburn would have given them one hell of a game and I say Auburn would have won. I know this is opinion only because the BCS hasn't let it happen. I still don't see where everyone sees all this strength in the Big 12 or the PAC-10. In the Big 12, they had OU and Texas. The next closest team was 7 wins, like the team we killed in the Cotton Bowl. The Pac-10 had USC and Cal, next closest was 9 wins(AZ state). In the SEC, we had Auburn and TN, plus UGA with 10 wins, and LSU with 9 wins. By the way Auburn beat all of these once and TN twice.
No way around it, Auburn deserved their chance and, since they didn't get it, no one can really say that USC is the best in the land. I know the polls do, but these are the same guys that had Auburn ranked 17th and 18th at the first of the year.
