On the point about interest… we have had 8 years of 4 teams in CFP. 32 spots. Bama (7), Clemson (6), Oklahoma (5), and Ohio state (4), have filled 22 of the 32 spots. 2/3 of the time it’s been 1 of those 4.
Expand the playoff to X number of teams and perhaps 2/3 of the teams will be 1 of X number of teams.
(I’m not mathematically saying this will be true but we all know there will be some group of teams that literally makes it every year, some that make it most or roughly every other year, annnnnnd, larger groups that make it once every couple years, and the largest group that makes it once every 10-15 years or even longer than that.)
So yeah, that ends up getting boring to a subset of people, typically those who fell in love with the sport when it had a totally different format.
“I loved you for so long but now you’re a completely different person “.
It’s understandable that many will lose interest and become less of a fan (I’m in this bucket) or no fan at all. Collateral damage unfortunately. Many more will join in for various reasons. For example, a co worker for years never watches college football except for the occasional championship but loves the nfl, he’s been telling me for YEARS that they playoff needs to expand, “more teams will make it more interesting” etc etc. I tried explaining various reasons for the beauty of the bowls, but it didn’t resonate…
