all that said, it's a pipe dream. there is ZERO chance that 4 leagues would be able to coordinate closely enough to come up with a nicely buttoned up 4x16 or 4x18 set up. they would all fight over members, some would refuse to take certain schools, etc. no one wants to be told what to do. i still think the B1G would stay at 13 if they somehow landed Notre Dame just to show people that they don't have to conform. they can make 13 work and we all have to like it.
these are 11 (5 really) independent leagues with no commissioner overseeing any of them collectively. no chance we EVER see some well-organized, uniform structure amongst all of them. NONE!
