What are the odds that the Big 12 regular season champion will get knocked out of a playoff spot by losing the Big 12 championship game next year?
Big 12 basically just needed a championship game; works for me.
A conference like the B1G won't be putting the two best teams in the championship since it's mainly OSU (if they get things figured out) and Michigan.
The North/South of the old Big 12 didn't necessarily put the two best teams against each other either, so this format is fine.
