I think the tension of the regular season is overrated.
I don't. There are two reasons I don't like watching the NFL. One of them is that so many of the teams make it to the playoffs, so they really only need to win 8 or 9 games during the season. I would hate it if 16 teams made the NCAA Playoffs. When I was a kid I used to actually pray for teams ahead of Nebraska to get knocked off. I watched every game between teams ranked ahead. I even figured out after we lost to Colorado which teams needed to lose to who for us to still make it to the championship game. All of that goes away if the playoffs expand that far. I'm okay with a 6 team playoff but not more. Last year I watched 1 NFL football game.
I like the NFL but agree that the playoffs don't need to get too big. Football is a physically taxing sport. You should be rewarded for winning almost every regular season game and not have to prove you're better than the 16th team in the nation again in a playoff.
I've long been a proponent of a playoff because there is simply not enough cross-over games in the regular season and too much difference in strength of schedule to say with any certainty that one team is definitely #2 and another is #3. Same argument - to a lesser extent - with the #4 and #5 team, as we've seen the last two years. I've had 8 as the number for years. I think six would work but I don't think giving two teams a bye will ever fly.
But no more than 8 teams. That catches all the one-loss teams so you aren't completely penalized for one game. But you still have to win basically all your games to get in. If there would have been a 16 team playoff this year, the last teams in would have been Northwestern, Michigan, Oregon and Oklahoma State. Not bad teams but there was nothing about their regular season that said they should still have a shot at the national championship - or making Alabama and Clemson play an extra game to prove they were better than them. But I do think Stanford and Ohio State have a argument that they were championship-caliber and deserved a shot on the field, which they would have had with an 8 team playoff.
I'm a fan of college football. I love seeing more games. But that's what the bowls are for - not too big of a playoff.
The prestige of the bowls has been diluted and isn't coming back. But I don't see the need for more. I still think it should be somewhat of a reward so I'd like to see (mostly) teams that are at least .500 getting the invites.
