I said before the ACC should dissolve, and join the Big 12, or reform under a new name and negotiate a better contract.
If the ACC were to dissolve and try to create a 'best of' new league with the most valuable Big 12 members, you can count on BC and Wake being dropped. And they would not be the only ACC members dropped.
I think that if such a thing happens, 16 members will be the largest the new league will gamble on.
Football is
MUCH bigger than basketball, which means the new league would have to built upon football, first and second and perhaps even third. Football wealth and power are best measured not by wins, not even over the past decade or so, but by average attendance and proven TV drawing power. State Flagship and/or Land Grant schools are always valuable (assuming they have programs they have invested in). States that have proven love of CFB and that produce a lot of football talent are valuable.
Based on the above, the Big 12 schools I would most want in the new league are: TTU, TCU, Baylor, Houston, Oklahoma St, WVU, Cincy, UCF.
KU is all about basketball, and the ACC has more than enough of that. K-St is a #2 school in a small state that produces very little football talent. ISU, which has super fans for both revenue sports, is a #2 school in a small state that produces very little talent. The states of KS and IA bring nothing, and their location is good only for the BT and for the SEC if it wants rivals for Mizzou.
Baylor has a great location in the heart of TX and has top programs in both revenue sports. TTU is a second fiddle A&M, and is out in Lubbuck, but TTU also has top programs in both revenue sports, and its largest alumni base in DFW. TCU is within the extremely important DFW TV market and has had top football and baseball and some hints at good basketball.
I am less certain about Houston than the 3 above, but Houston also could be a top school in both revenue sports.
Ok St is a Land Grant school and has many alums across TX. Ok St also has Pickens as major sports booster.
WVU has very passionate fans in both revenue sports and if playing a mostly ACC schedule would add passion to the league. WVU has significant TV fan bases in Baltimore/DC, across VA, Pittsburgh, Charlotte, and southern OH.
Cincy is the overall #2 school and sports school in a large state filled with lovers of CFB and with football talent.
I think that the very best the ACC could do in saving ACC members while trying to forge a 16 team new league is to get WVU, Cincy, TTU, TCU, Baylor, and Ok St. Then the ACC would need to cut 2 more in addition to Wake and BC.
