How did Marist sneak in there?

Richmond already bailed on A10 Football during the tug of war with the CAA in 2005, there's no reason to believe they'd join a new A10 league with a weaker and more geographically disparate group of teams.

Temple obviously is in the wrong subdivision, unless they move to FCS. The only program currently capable of going in the other direction is UMass, with Charlotte in play starting around 2017. I don't believe Temple would move down, nobody ever has moved down voluntarily except Holy Cross I think, and that was shortly after the two subdivisions were created.

The other A10 members are all running low budget, low attendance operations. Delaware only cares about football, they're not going to leave the CAA for that group.

If the A10 ever again starts another football conference, it will be because the CAA broke up and it will consist of UMass, URI, UNH, Maine, Stony Brook, maybe Villanova, and maybe Albany (especially if Villanova is out). Fordham I bet would be given the option of joining if they went full scholarship, but I don't know that they'd leave the Patriot League. I think the rest would be too far away and/or disinterested, but I'd welcome Charlotte if they wanted to play with us Northerners.
