No man. 3 bids is what we expect and what seems to be the average. More than 3 is great, but 3 is in no way a disappointment almost any year.
But you're right about the CAA. George Mason has a historic run to the Final Four in 2008. But in 2009 and 2010, they got zero at-large bids, with both auto qualifiers getting 11 seeds. The CAA, just like any other conference on the outside of the BCS-6, need momentum. Success is gauged over time. And in time, if there is some momentum built, than there will be a reason for Charlotte to consider the CAA.
In the meantime, I think eventually, the CAA will extend a football-only invite to Charlotte. Just playing hardball now. But if UMass and Nova follow URI out, and the CAA needs football-only replacements, there are really only 3 options:
Charlotte: wants football-only, plans on upgrading to FBS eventually
Stony Brook: wants football only or all-sports, would jump at chance for football only invite
Fordham: wants schoolies, means out of Patriot, wants to remain in A10 for other sports...CAA best option
YSU: sure, CAA might want them for football only but would YSU leave the MVFC? doubtful.
App St: would need to be all sports but AD gone public ag. CAA, saying they'll only leave SoCon for FBS conference
GA St.: would need to be all-sports, but CAA not looking all-sports
Liberty: likely same boat...would need to be all sports CAA since Big South has football
Coastal Carolina: similar to Liberty
list can go on, but really you've got 3 candidates
Maine, UNH, Towson, Delaware, JMU, W&M, ODU, GA St
If youre comfortable at 8, it's all set. If you want 9-10, I see Fordham and Stonybrook as the best bets as you can try to schedule the 4 northern schools vs each other most years.
