No more than two teams from a conference may be selected, regardless of whether they are automatic qualifiers or at-large selections, unless two non-champions from the same conference are ranked No. 1 and No. 2 in the final BCS Standings.
Based on that rule, if LSU and Alabama both win out their regular seasons (which is probable but obviously not guaranteed) and then Georgia somehow finds a way to win the SEC Championship over LSU, the SEC would likely be able to send a 1 loss LSU and a 1 loss Alabama to the NC game (SEC NC Thread) AND send Georgia to another BCS game as an AQ. In my opinion, the fact that this scenario is even possible is just another reason why the current BCS system is ridiculous. Georgia is not even the third best team in their conference, but they are a fluke away from getting a BCS bid. I am still yet to hear a reasonable argument for why we can't just take the top 8 teams and have a playoff. That gives us 7(!!!) meaningful games, which we can still call bowls and rotate them between sites, instead of just 5 (only 1 of which is truly meaningful). We can still also have all of the other bowls for everybody else that nobody watches unless your team is in it. So, if you aren't a top team, your motor city bowl is just as meaningless as it used to be. Another benefit to the playoff system is that there would be less pressure to be perfect, so we might see fewer cupcakes in the non-conference schedules.
Anyway, those are my rants on both the SEC and BCS merged into one post. Discuss amongst yourselves.
