It's really been the super conferences that have killed what made the sport so great, which is its tradition(along was with $$$). Gone were A&M/Texas, WVU/Pitt, Kansas/Mizzou, Nebraska/Colorado, Nebraska/OU, Maryland had great CBB rivalries in the ACC, and there is huge fan apathy there, having known a bunch of Maryland fans(I'm sure I'm missing some others). It's even affected a team like ND. We had great schedule back in the day, typically 3/4 B1G teams. 3/4 Big East teams. Navy, Stanford & USC. Then fill it out with a couple other teams. Just comparing ND's 2003 schedule to next year.
2003: Washington State, 3 B1G teams(Michigan, MSU, Purdue) 3 Big East schools(Pitt, BC, Syracuse), Stanford, Navy, USC, 2 Others(BYU, FSU).
2023: Central Michigan, Tennessee State, Ohio State, USC, Navy, Stanford, 6 ACC schools(Clemson, Wake Forest, Duke, NC State, Louisville and Pitt)
That's like 6 games next year where I'm already disinterested in(CMU, TSU, Duke, NC State, Wake Forest, and Louisville)
I'm hoping with the 12 team model, we get more important Non conference games, where losing a game doesn't make you need to win the rest. Big games are what makes the sport so great, we've lost out on a bunch of rivalry games over the last decade, so now hopefully they can be replaced with better marquee Non conference games.
