Please see my post 638 to see why this was ruled out by the BCS rules.
Team-Selection Procedures
The bowls will select their participants from two pools: (1) automatic qualifiers, all of which must be selected, and,
(2) at-large teams, if fewer than 10 teams qualify automatically. The following sequence will be used when establishing pairings:
1. The top two teams in the final BCS Standings will be placed in the National Championship Game ("NCG").
2. Unless they qualify to play in the NCG, the champions of selected conferences are contractually committed to host selected games:
Atlantic Coast Conference-Orange Bowl
Big Ten Conference-Rose Bowl
Big 12 Conference-Fiesta Bowl
Pac-10 Conference-Rose Bowl
Southeastern Conference-Sugar Bowl
3. If a bowl loses a host team to the NCG, then such bowl shall select a replacement team from among the automatic-qualifying teams and the at-large teams before any other selections are made. If two bowls lose host teams to the NCG, each bowl will get a replacement pick before any other selections are made. In such case, the bowl losing the No. 1 team gets the first replacement pick, and the bowl losing the No. 2 team gets the second replacement pick. If the Rose Bowl loses both the Big Ten and Pac-10 champions to the NCG, it will receive two replacement picks.
A bowl choosing a replacement team may not select any of the following:
A. A team in the NCG;
B. The host team for another BCS Bowl;
C. When two bowls lose host teams, then the bowl losing the number one team may not select a replacement team from the same Conference as the number two team, unless the bowl losing the number two team consents.
According to Gerry Ahern of Yahoo Sports, this is the reason why Georgia wasn’t picked to play in the Rose Bowl against SC (BTW, he’s not the only analyst who has said this):
“The BCS did its best to seal the Trojans’ fate by pitting them against Illinois instead of Georgia in the Rose Bowl. The RIGGED system hoped to quell any chance for controversy over the validity of the Jan. 7 championship game. Instead it served to deny the nation a more interesting Rose matchup that would have better quantified how good USC and Georgia are.”
