Have any private schools upgraded to I-A since the creation of the I-A and I-AA classifications in 1978? I can think of multiple incidences of private schools leaving I-A (Villanova, Drake, Richmond, Colgate, the Ivy League, Furman, Pacific), but what about private schools joining I-A since 1978?
Upgrades since '78 (by conference)...
Cent. Fla 1996
(Marshall was originally 1A and went to 1AA and is now back)...
All of the MAC was briefly 1AA for one or two years back in 1982(?).
Boise St. 1996
Troy St. 2002
I believe none of these are truly all private, but am not familiar with all of them. Should answer Yungs question though (?)
