From another perspective. Remember, both Coaches K and Pitino like the idea and they have about 500 years of experience between them. You cannot risk being left behind.
Both the Big East and ACC have blue blood programs, excellent programs, good programs, and dregs - your bcu, depaul, etc. A combined league by sheer numbers would have more top-notch perennial ranked programs than the SEC, Big 10, or Big XII. That feather in the cap alone is worth a premium bonus since it would be THE premier basketball conference. As it is now, the two conferences are number 4 and 5, or 5 and 6. That sucks. So there is a lot of brand marketing value there. If you ain't first, you're last.
Plus, and I know some will disagree, the merged conference would get an additional boost by uniting major markets Chicago, Indianapolis, NYC, Hartford, Boston, Philly, DC, Cincy, Atlanta, Charlotte, Miami, Dallas, Frisco, etc. So, numbers, logistics, synergies, rivalries, all that sheet. It would be one hell of an amazing basketball conference and there is no question, it would put like 10 - 15 programs in the dance every year. If you overlayed the Big East and ACC maps, it would blanket the entire eastern and central time zones including every major city. And that's all that really matters, especially when it comes to basketball.
Finally, the way the football CFP plan is going, the Big Ten and SEC are forking it up for everyone else anyway. Most of the ACC is virtually shut out as is the Big XII. I mean, FSU was literally shut out last year. If the Big Ten and SEC break away, whatever happens, the ACC/Big East toes are still tappin'. A 28 member basketball conference will not only never be left behind, it would be calling the shots vis-a-vis the basketball tournament. The Big Ten can go home and get their freaking shineboxes.
That's my opinion and I'm sticking to it.
