MAC and SoCON both would make sense for Morgan State, from a georgraphical standpoint. From a logistics, I am thinking SoCON makes a bit more sense.
I also would like to see the MAC get one more school, somehow, to make an even 14. I had dove in to it at 3:00 AM some time ago and I do think some of the EIWA schools share a conference with some of the MAC affiliate schools in other conferences. I might be dreaming here. It was a while ago I was looking at this, so it might be wishful thinking.
Actually looking back at it now (briefly) it looks like Bellarmine and App State are affiliate members for other sports, so perhaps Bellarmine to MAC looks a good fit to get to 14.
