It's not the winning, it's the money that football brings in to the schools. Money is the reason that they expanded the playoff from 8 to 12 and before long it will be 16. The conferences and the schools like Alabama and Ohio State that will get in on a yearly basis want that extra money and the fame that goes with it. Basketball will never have that pull, no matter how many championships schools from the Big East win.
The NCAA tournament brings in just about as much money as the CFP. The basketball conferences could push to have an independent tournament similar to the CFP with the revenue going to the conferences rather than the NCAA. But that would be the end of the NCAA and Olympic sports championships. Cause that’s what basketball pays for.
