For those that wanted a bigger expansion, take heart that this is about the only direction things seem to move, and they will eventually expand again. First there was no championship, then it’s a four team playoff, now 12 teams. Just like with the NCAA basketball tournament, the World Cup, the baseball playoffs, NBA playoffs. The movement is always to include more teams in post-season play, not fewer.
Though the power conferences will do everything they can to tilt the new format in their direction, it’s still an improvement.
