There definitely has been -- in fact, the CAC should be sponsoring football the moment that CNU hits but the CAC has been delaying this decision because there aren't enough schools for an automatic bid, or enough unattached schools for them to draw on.
CNU, Frostburg, Salisbury and Wesley make four, but they need seven for an automatic bid. There aren't any other independents to loop into the league.
I had heard that there were perhaps other USA South teams that might be interested in making the jump to the CAC, but haven't seen any movement on that in the 12 months since a few names were floated my way. Perhaps one of the schools will add football, although I have heard nothing, not even rumors, on any of those.
