I don’t know, I suspect if you polled BCU fans would they rather have for national championships or none, and they were honest, they choose for national championships. Likewise, if you polled Syracuse fans, and they were honest, they say they would rather have for national championships then well, one with an asterisk next to it.
Now, don’t get me wrong, I think most Connecticut fans would move to the ACC if offered, though I suspect many, like myself would prefer the Big Ten, just to have the financial security. But for fan experience nothing beats competing in winning national championships. Anyone who says otherwise is being disingenuous.
