Starting a brand new league would be incredibly difficult but I 100 percent agree the best conference for UB is one that doesn't exist (yet)
To me it would make more sense/easier to expand the Mac to the east coast, imagine if they were able to add temple, UMass, and if you're looking into acc schools a Boston college or another bigger fish like uconn
If the Mac has no interest in expanding UB needs to start looking elsewhere but I don't believe that the Mac doesn't want to expand
