The A10 is not the A10 anymore. Back in 1991/1992, the A10 was Rutgers, UMass, Temple, WVU, URI, GW, St. Joe's, Duquesne, St. Bonaventure. All Northeastern schools stretching from Washington DC to New England. Today, the A10 has schools in Ohio, North Carolina, Illinois, Missouri, Virginia.
The A10 has lost most of their best basketball programs over the years and there were rumors they might lose Dayton and/or VCU to the Big East. If UConn ever got a P4 bid, the Big East would raid the A10 and add 2 or 3 schools. Was there a LT future for UMass in the A10?
I've talked to a friend (UMass grad) about the move to the A10 and he thinks it is a short term move. He thinks UMass needs to stabilizes football and then hope that conference realignment in the future will give them an opportunity to move up. May or may not happen, but there was no hope staying in the A10.
