Just opinion but, not a very smart move. Back-to-back final appearances can do better than the A-10. I do not see it happening. Although the A-10 dropped FB, so that hurdle is "jumped".
Not really sure they can do better. Without football the Big 6 conferences are out of the question. Unless they wait for the Big East football schools to break away and try to align with the non-football schools like St. John's, Georgetown, Nova, DePaul, etc, I don't know where else Butler goes. As I saw mentioned elsewhere, this is the first conference move in a long time not being driven by football.
8 of the top 10 Sagarin conference play, or pretend to play, "big time football." Only the Atlantic 10 (#7) and Missouri Valley (#9) do not. The West Coast Conference is #11 and the Horizon is #12.
I think the Valley would force Butler to really step up the non-basketball spending and performance. The overall depth of the athletic programs seems far greater than that of the Horizon. And is the Valley, with its college town teams, what Butler wants? I don't know how many alumni are in Carbondale, Cedar Falls and Springfield versus Philadelphia, Cincinnati and Pittsburgh?
