This is so much better than the BCS. But what they need to do is cut down on Bowl games. With the larger playoff field, you should now need like 8 wins to be bowl-eligible. And cut down to like, 20 bowl games or something. Ain't no need for all these irrelevant bowls, and the bowl season would be interesting again, if teams who missed the playoffs, but won 8+ games, were the only bowl eligible teams...
12-team format is perfect. Also do away with all conference championship games, you don't need em with a large playoff field...
