It still wouldnt accomplish anything. But even if I bought your argument, It would take a month to play out a 16 team playoff bracket. Are you going to just add that onto the back if the season?
I wonder what happens when some heisman trophy winner shreds his knee and ruins his nfl career because a bunch of spoiled college football fans want their delusion of fairness.
There’s already a month inbetween the end of the season and the championship game, all a 16 team playoff does is put meaningful football in that gap that’s currently occupied by air and bad bowl games.
