If you look at some recent changes for instance Wichita State or Creighton there were some baseline reasoning behind each move.
WSU had / has been on a run for sometime and noteworthy in any sporting news cycle.
Creighton was a connected Jesuit school doing moderately well (not as well as WSU obviously).
So we see two compelling reasons (among others in the decision to invite) that caused these teams to move into a different conference.
Unfortunately UD is still trying to string together a run similar to WSU's program and we don't have a natural affinity to say a Jesuit leaning conference.
Secondly this year appears to be a re-build
and hopefully we get back into some tournament discussions next year. But this will only extend the time where we can say we have a sustaining hi level program year after year.
As for some affiliation we could look into a national Marist based conference. There is a Marist school in NY and I know there is one in Honolulu so we have a national conference immediately!
