Basketball has a top 25 ranking and a championship game. That's not a fundamental flaw. The rankings are used to determine who gets to play the game, and the game determines who the champ is. A 4-team playoff doesn't eliminate controversy, but it certainly reduces it. If you take the top 4, that eliminates the controversy coming from the top 4. There will be bitching by the 5th/6th ranked teams, but I say too bad. If you didn't play well enough in the regular season to be ranked 4th, that's your own fault. And if you ended undefeated but were not ranked, schedule better opponents. The biggest problem with a large playoff is there is no motivation to schedule meaningful out of conference regular season games. The regular season is still the bread and butter of CFB, and I think it should remain so. I think it will change with a +1 game, then a playoff. The BCS setup was the first step in the gradual transformation away from voting for champs and playing for champs. A 4 or possibly 8 team playoff is the inevitable end. Anything larger than that would be absurd. The basketball top 25 isn't as important during the season and is meaningless once the tournament starts. Not so for college football, where the poll is still seen as important after the season ends. And the basketball poll doesn't fully determine seeding. I don't think it really reduces it. You'll have more teams claiming they deserved a spot in the 4-team playoff. It could be said that such controversy would be better than it is now, but you'll still have more of it. With that said, there's always going to be more controversy in college football than in any other sport.
