Why are 4 or 3 conferences better than just joining 1 conference? Divide into whatever regional groupings make sense for any given sport. Have several television stations and negotiate rights as one organization.
The distractions over who might leave will be gone. We can stop the pissing contests over who has the highest rights deal.
Football, basketball, and baseball tournaments for a P1 conference would be more competitive than what the NCAA has now.
A few multimillion dollar commissioner jobs might be eliminated so I'm not sure it will happen but it should.
