First, the ACC is going to get rid of divisions. Non-factor.
As for conference, the conferences are getting larger. Is Jumpman always going to stick with the same 5 or 6 schools? If not, can you find some natural contrasts? Florida has the far east side of the SEC, Oklahoma the far west. North Carolina could be the mid-Atlantic smaller-town public school, Miami the far southern big-city private school. I have no idea who else would appeal, stylistically, in the Big 10, so if not boring Ped State (and let's not pretend Michigan unis aren't boring), then what about big-media-market Rutgers or Maryland (a death-blow administered to Under Armor)? And as for the Pac 12, the only one that makes sense, and isn't in Oregon's backyard, would be Colorado.
Anyhow, getting ahead of ourselves here. All I really care about is Miami.
