Because there's over 130 teams that play and you think only a dozen matter. No, there aren't 15-20 teams in November when only 8 get in. At max there's 12 in contention so 120 are playing for pride. You don't comprehend this isn't about the elite teams. It's about all of FBS. You're simply wrong because of who you root for. The more teams in the most season mean more game matter. There's no argument against that. You care more about a team trying to be undefeated which should have never been the goal.The teams that have a realistic shot like the top 25 or 30 it does matter. #48 in the country? Who cares. Yep as you get down to November there will be about 15-20 teams vying for 8 spots. It weeds out the weaker teams who never were going to win anything. The best teams playing games that matter. Not mediocre teams trying to get spot #23 in the playoff so they can get crushed on the road by a top 8 team in the first round of a playoff.
The regular season of college football was always inflated by fans simply because they hate change. This post and others prove that.
In an 8 team playoff last year only the SEC Big Ten and ND were relevant. So, let's make that the league then BUT until that happens what you want will never work. It will and should continue to expand. 24 is the sweet spot. Just like FCS has proven.
