ACC IS NOT THE BEST FOR MIAMI.The TV market for NC(4) members and Clemson (1) member is a POOR TV market.The TV market for MD is good and for GA TECh is good.However,the majority of fans in Georgia are for the UGA.Fl ST is good as long as they are a national team.After that it is not so good.The money from tha ACC comes bb in NC.The TV market VTECH is worse than Clemson. If Miami stays with Syracuse and BC the new 12 team BE will be stronger than the current BE.The football league will consist ofUCONN,Temple,Rutgers,WVU,VATECH,PITT,BC ,Syracuse and MIAMI.Probably ND who will be given a sweet deal.(also the remaining 5 bb only schools want a minimzed travel budget)That will be 10.The there will be Louisville and Cinncinnati.Miami's travel expenses will really go down with a 2 division setup.The northeast tv market is clearly superior to the ACC.10% of NY/NJ is better 50% of SC.Also to help get ND into football there will only 7 league games.
Not debating the TV market angle, but that same "poor" ACC market provides the most money per-school thus far, and that's what matters to the schools trying to fund their programs. Add to that any quality expansion teams and their markets, plus the additional national air-time that comes with league upgrades and there you go. Miami vs. BC would be just as attractive as an ACC game as a BE game, and Miami FSU would take on larger status for divisional reasons.
Regarding your points about the probable BE expansion counter-proposal. Again, I agree with you that such a proposal would be better for Miami but it is dependent on some hefty "if's"; ND feeling the need to join any conference, and the likes of Temple, L'ville and Cincy saying yes to the BE before going elsewhere. Ironic that Miami could be willing to put itself into a position of dependency on what the Irish may-or-may-not do! Can the BE truly afford to give away even more $$ and/or conditions to both Miami and ND? Would ND be better off with the new BE or with either the BE or ACC losing its BCS bid?! And if the BE could offer ND the chance to keep so many ooc games to appease it's national audience, the ACC proposal can do the same for Miami.
As for the travel cost, I don't see how Miami's costs would go down much, if at all, in the new BE divisional format. VT and WVU remain your closest opponents.
I trust that all the AD's involved will do what makes the most sense financially. It may not be what we want for conference affiliation, but these are schools first, sports programs second.
