You use the Sun Belt as the model. They just added 4 schools - Marshall, James Madison, Old Dominion, and Southern Miss. All but Southern Miss are bowling. They added Texas State, Georgia Southern, Georgia State, and App State all in the last 10-11 years. There may be others that I'm missing, too. Point being, they are the exact model for how to make expansion work.
I agree with your assessment of their 9 game conference schedule, creating scenarios for more teams to go bowling, etc., but that all started with expansion for the Sun Belt, and the MAC is failing to do that. Western Kentucky would've been bowling for the MAC had we added them.
You mentioned Jacksonville State not making the MAC more interesting. Newsflash - they're bowling this year and have been a phenomenal story all year. What happens when Rich Rod leaves? Who knows. But they're a school that is showing they want to be competitive by bringing in Rich Rod in the first place.
The MAC is made up of a bunch of schools with P5 schools as their neighbors. They have to find a way to add schools that break that mold and take the MAC to new heights.
Adapt or die. The most dangerous words in business are "We've always done it this way." That's MAC's motto under Steinbrecher, except he uses slightly different verbiage. "We pride ourselves on our history and tradition." 🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮
