My dad taught at MC (his alma mater) for several years after retiring from Hinds, and one day I went to have lunch with him there, and we wound up eating with the college president (this was probably 15 years ago at least). They were still D3 at the time and we talked about the complexities of changing divisions. They had done a study about NCAA classification options for them and the one thing the president said that stuck with me was that for the costs associated with scholarships at the D2 level, they'd actually financially be better off going to FCS because it's not that many more scholarships than D2, and you can get big buy checks from FBS teams to help with the costs.
