I was looking at TCU's scheduling setup.
The Big 12 plays a 9-conference game schedule, round robin (everyone plays everyone), in turn allowing only 3 OOC games.
TCU has done a pretty good job scheduling their OOC opponents. While one of those 3 games each year is an FCS opponent like everyone else, they had Minnesota (which turned out to work in their favor this year) in the first year of a home and home, with upcoming home and home games versus Arkansas and Ohio State.
They also are scheduled to play SMU yearly, a traditional rival.
Anyways, possible changes:
A) The NCAA grants the Big 12 a waiver to play a conference championship game with 10 institutions.
(This seems the pretty likely scenario, especially given the NCAA's lack of teeth at the moment. I'll be honest that also - given the Big 12's desire to continue to have all 10 teams play each other round robin - it also comes out kinda...weird. Any championship game would be a rematch of two teams that already played, every time.
Yes, it provides a 13th game...but it opens up plenty of "how much did the first matchup matter" issues, possibly negatively effects SOS, and even leaving open possible "both teams will just play each other again next week.")
B) The second scenario might be for TCU to further adjust its OOC scheduling (in the case the other scenario wasn't passed). They'd begin to schedule 2 power 5 OOC opponents each year as part of their 3 OOC slate, to "make up" (which seems odd to say, considering they're really only playing 1 group of 5 school each year, while most play 2-3).
In short, this would mean TCU would need to open up that 2nd OOC game slot by either (1) becoming the only FBS team to not play a yearly home game against an FCS opponent or (2) buying their way out of their future contracted games with SMU through 2017, their historic traditional rival from the Southwest Conference days that they've played yearly since 1926.
