Go big - get Texas, Houston, Oklahoma, Oklahoma State, Kansas and either West Virginia or Kansas State, I prefer WVU for argument sake. Keep ND as is. Create two ten team divisions. You could add WVU, Texas and Houston to Coastal. Add OU, Oklahoma State and Kansas to Atlantic. Or, put the 4 NC, 2 Va and 2 Fla schools plus GT and Clemson in the Traditional Division and all the rest in the expansion division. Your conference games that count are your nine division rivals. Three teams per division play ND each year. The other seven in each division schedule one crossover game. It does not count in the standings but gives TV volume to work with. That's ten good games for everyone. Some will choose to play a rivalry game with a quality opponent. TV will love this. We would lead the way to four mega-conferences and would have gotten the best of what is out there.
For other sports go to three seven team divisions. In basketball you play your division twice and four teams from each of the other two divisions for a twenty game schedule. Again, more volume for TV. Have a two weekend tournament. First weekend at three sights - each division has a three day event. The next weekend bring the three tourney winners and the highest ranked team that did not win to play the semifinals and finals. Division 1 - Syracuse, BC, WVU, Pitt, ND, Louisville and Miami or Kansas, Division 2 - UVA, Va Tech, UNC, Duke, NCSU, WFU, Clemson Division 3 - GT, FSU, Texas, Houston, Oklahoma, Oklahoma State, and Miami or Kansas.
