With a 6 or 8 game format, think of all rematches you most likely end up with. With this years rankings, if UGA were to beat au... you coulda ended up with a 3peat matchup between the two in an 8 team playoff. You'd have to kill the conference championship game if you go that route, me thinks.
Maybe, maybe not. I think a 6-8 team bracket would give this committee a little more legitimacy of putting in a 2 loss champion. This was all about getting the Big BOYS to the playoff. You have the "Power 5" BIG BOYS and then the other Group of 5 "other guys". I think they would likely do away with one of the regular season games instead of the conference championship. Too much money involved in that weekend.
This season is a perfect example of the need for a 6-8 team playoff. 1 undefeated Power 5 team in Wisconsin. I know and the entire country knows that they played a weak ass schedule but they won the games on that schedule. 1 loss teams Clemson, Miami, OU, and UGA all playing for a conference championship this weekend. 2 loss USCw, Ohio State, TCU, and Barn playing as well. Then you have 1 loss Alabama that lost to the #2 team on the road in the regular season finale. Any school picking up their 3rd loss is done. All 5 conference champions would be in then 3 "at-large" bids awarded.
Like I said, they likely would do away with one of those creampuff weekends at the beginning of the season. Someone mentioned money and TV contracts. This would likely be restructured with how this is heading. 11 regular season games, 9 conference and 2 OOC + championship game. Use the bowls that are in the playoff rotation, leading to a title game that would rotate amongst those stadiums as well. It would give that city an opportunity to host 2 games as well.
Rose, Sugar, Cotton, and Peach are in the rotation. Let the Rose host the title game this year, next Sugar, then Cotton, then Peach.
