Virginia Union has only 1099 students, only 504 men. It's smaller than Chicago State. Their entire budget is $4,321,343, which is less than half the average of the MEAC. Their entire endowment is a measly $29m. They cannot support D-I. They need to be three times larger in everything. It makes no sense for them.

Kentucky State is equally small with only 1052 undergrads, (only 468 men), and a budget of $3,984,782
Central State is a bit larger with 2029 students but a budget of only $4,194,542

For comparison:
Norfolk State has 4,133 students and a budget of $13,709,708
Delaware State has 3,582 (only 1196 are men, heavy female tilt) and a budget of $12,457,825
Morgan State has 5,829 students and an athletic budget of $14,156,767
NC Central has 5,237 undergrad students and an athletic budget of $14,511,739

Virginia State is more plausible with 3,862 full time undergrads (although only 1,640 are men) and a budget of $6,149,071. They would still need to double their budget, which would be about $4,000 per student to support athletics, but it's not that much different than current MEAC members. The other four schools would need to tax their students $7,000 (Central State) to $14,000 a year to support FCS programs at the MEAC level.

The only viable option for an add is Virginia State, as Winston Salem State (4,111 students, but only 1,167 are men -- heavy female tilt; and budget of $4,286,679) took themselves off the table because they realize they cannot afford to D-I, as they tried before. Chicago State looks worse than the first three D-II schools I looked at and they are farther away, do not have baseball or football, so no help on critical sports.

So any MEAC add from D-II beyond Virginia State is DOA, and so far no indication Virginia State is really interested.

Note, SC State is really marginal on resources with just 2.152 full time undergrads an a budget half the other MEAC at $7,778,657.
