I think it is a GREAT sign that the MAC has stayed stable thus far. Lost Temple, but gained UMASS. I know, I know its UMASS. But they were actually a top FCS program. Other smaller conferences have done worse.. I'd really like them to join in all sports though, especially basketball.
I do not really see any MAC program getting targeted for what they see in terms of potential revenue gained. Like you said, there really isnt a team who dominates and also owns a large market. I just hope no programs are dumb enough to leave for another mid-major. We are showing potential.
