I wanted to share my thoughts on potential replacement members for the Sun Belt (from someone who appreciates the conference, though I'm not a fan). In no particular order:
Liberty: They would rank #1 in athletic revenue in the Sun Belt after JMU leaves, reside in the same state, have had recent on field success, and carry high name recognition. The obvious con is the "diploma mill" reputation and institutional baggage that most fanbases wouldn't want in the conference. Purely on paper, though, they make a lot of sense.
Miami (OH): After missing out on the AAC, they might look around if they think the MAC is unstable. Ohio sits outside the traditional Sun Belt footprint, but otherwise they would be a solid addition. Their athletic revenue is strong, they have rich football history, and their basketball team just made the NCAA tournament as an at-large. Adding them would also weaken a peer G5 conference.
Toledo: Most of the points for Miami (OH) apply here as well, proven athletic success and solid resources, with geography being the main hurdle for a middle revenue team.
Kennesaw State: Generated stronger revenue than both MAC schools last year and fits the Sun Belt’s geographic and cultural footprint naturally. Honestly, this might be the option that makes the most sense while actually being acceptable to current fans.
Multi-Team Scenario (WKU + MTSU + Kennesaw State): WKU and MTSU likely move as a package deal. Grouping them with Kennesaw State gives the Sun Belt three programs generating over $40M in athletic revenue that fit the regional identity seamlessly.
