I think you're selling Nova, PC, and St. John's short. I'll never understand the Neptune hire and why he's still there but I don't see Nova falling off the map. Programs go through lulls, hey it happened to us. Louisville is going through it. Nova is all about basketball and even with the changing landscape I don't see them going away. Their NIL is huge and they have enough money people supporting the program along with some really good NBA players who are all about their alma mater. Providence has really stepped up their NIL and it's the only game in town, their fanbase is rabid and they continue to get players. St. John's after being lost for a long time has a renewed commitment to basketball and financial backing. Georgetown, I'll never quite understand. They should be great but their obsession with never moving on from John Thompson has destroyed them.
Even with all the changes as long as something crazy doesn't happen and the NCAA tournament is scrapped I don't see these Big East schools being marginalized. They are basketball schools, it's their identity and not having to worry about football and the money that goes along with it should enable them to keep strong in basketball.
