There may be - but it wouldn't be about football. CAA Football is a distinct entity, and still maintains its original 250K exit fee. It would be a poor decision not to join up as at least a Football only member ASAP, as it seems the Big South's days backing football appear to be numbered.
Frankly I don't mind us pulling a Delaware or Gonzaga for a few years if it means more money, larger fan base, larger stadium, and ultimately an entry to a more financially profitable FBS conference (ie. NOT the MAC)
