The playoff format definitely needs a little tweaking. Even if you wanted to continue giving conference champs a bye, you could re-seed after the first round games, so you don't have a Boise or ASU as 3/4. Also, it seemed very odd to me that the teams that earned byes then missed out on having a home playoff game. Not exactly sure how you fix that part, but an oddity nonetheless.
I attended the championship game with my son (who is an OSU student). The crowd, the venue, the game, it was all great. Besides being really cold (in the low 20s and windy), my only complaint is that a lot of the area bars/restaurants were closed for private events. I can't imagine how much it had to cost for places like that to close and miss out on all those customers. It made the places that were open really crowded, especially since no one was tailgating outside due to the weather.
The game was so great though. We definitely got a bit nervous when it was just a one score game and it looked like we would have to punt it back to ND with ample time on the clock. Then this happens!
