The A-10 really doesn't do it for me, and that isn't even considering what it would mean for the football program. Like B&G, I get genuinely excited about playing Portage Community College, OU, Buffalo, and Toledo no matter the sport. Those are good, regional rivalries we would lose by moving. I also agree the directional MIchigans and NIU bring little to the conference.
I would much prefer the conference find a way to elevate themselves to a two bid league so it all doesn't come down to the tournament. Marshall and/or JMU would both be great additions for football and basketball, but I don't think adding quality programs is going to change national perception. I think it boils down to what the conference does in the OOC and tourney. Meaning make some noise consistently for a few years in a row. Buffalo went to the Sweet 16 a few years ago and hasn't fell off a cliff after losing two coaches to P5, OU took IL down to the wire, PCC took VA to OT this year. Also avoid the losses to the bottom feeders in conference play. I don't think the conference is too far off, just need to find a way to take that next step. Unfortunately money is the reason likely preventing us from taking it.
