I don’t think a PAC-MWC merger is a threat. Even with SDSU, Gonzaga, St Mary’s, Memphis, they’re still only the 5th best b-ball conf. Besides it appears now that a PAC-ACC merger is more likely.
Also….and this may sound cynical, disloyal and ruthless, but should another conf, say B12 or B10, feel sufficiently threatened by the prowess of the BE and decided to destroy it, it could only be done by taking Stj, Gtown and Nova. Taking UConn alone would leave us as still a perennial top conf.
In this scenario, St Johns in NYC, with MSG as home court would be just fine and will always reside in a major conf. Posters here continually knock UConn for it but we too would put our school interest above the collective conf should the opportunity arise.
Schools like Hall, Marq, Prov rely on the continued existence of the BE.
