I want to be outright, but there is a part of me that would like 2 Big 12s in the BCS too.
In a few years, no one will remember how many teams from the Big 12 made it to a BCS game during the 2012-2013 season. A handful of people will know who the Big 12 Champ(s) was/were, but hey, that's more than no one.
