We were the northern outpost in a southern mid-major league. We had no rivals, travel for non-football was brutal, and the fanbase did not know or care about UConn's opponents. UConn got cut off from NY/NJ for basketball recruiting. It was a horror show. The program did a 180 as soon as it announced it was joining the Big East. Also, Auriemma HATED the AAC.
It would have been a lot easier to be a football independent 12 years ago than it is now, and we could have used that window to manage the football program more effectively to improve its media presence in the northeast.
At this point, I assume anyone that says the AAC was not a catastrophe for UConn athletics is just trolling.
