The chances of this actually playing out are beyond slim, but the possibility exists and I really don't know how this situation would be handled by the BCS. I have not heard of this scenario from any type of media source so if this has already been addressed please let me know.
Current BCS rules allow no more than 2 representatives from any given conference in the BCS bowls each season and one spot is guaranteed to the champion of each of the 6 big conferences, so what would happen if LSU loses in the SEC championship game by way of a last second field goal to Georgia giving the Bulldogs a guaranteed bid into the Sugar bowl? Now lets say Oklahoma State drops their final game to Oklahoma, Stanford loses to Oregon and the ducks go on to win the Pac12. For my experiment I am assuming Houston does not stand as any kind of threat.
Boise is now the only undefeated team in the top 8 and the other 7 (Alabama, LSU, Oklahoma, Oklahoma State, Oregon, Stanford, and Clemson) are all sitting there with 1 loss. What would the polls look like? Who would the computers decide is the best? I am going to pretend that there is still a large amount of backlash at the thought of Boise in the championship game as evidenced in this week's polls, Bama lost an ugly game to LSU and stayed ahead of BSU in the coaches poll. For the ultimate chaos scenario to play out the voters need to decide that LSU and Bama are still the best teams in the country with 1 loss each and the rest of the top ten looks something like this.
3) Boise State
7) Oklahoma State
9) Penn State
With Alabama and Georgia both having guaranteed bids and both coming from the SEC, LSU would be ineligible to participate in the NCG even though they are the #2 team in the country. Can you imagine the outcry from the SEC elitists? Would this be the final nail in the coffin of the BCS? Is this what needs to happen to finally get a playoff implemented in college football?
