If Murray leaves, no winner of the OVC will sniff a 13 seed. With Murray, a 14 is possible. Without Murray, the winner of the OVC will probably 15 at best and will more often than not end up lower than that. Honestly I wouldn’t be shocked that once Murray leaves, you see the remaining members of the OVC cut their budgets.
Make no mistake though, you’re point is valid. Some team will have to win it. Just like the SWAC, MEAC, and the NEC. That is no promise of being a national brand.
