Is your official position that the Big East was not a major conference in 1999?
My official position is that UConn was a member of the Atlantic 10 football conference in 1999.
It is also my position that 30 years ago from now (and where you wrote the post to which I responded), dates back to the 1990-1991 season. Duke won that year and from then on, only UConn and Villanova have won men's basketball championships as members of a conference outside the P5(6).
It's an argument I know well. I made it for nearly a decade. Major Championships are difficult, if not near impossible for programs without at least a Div. 1 football program. It 100% had to do with money, which really only started to flow primarily through football in the early 90s. This is what gave the 'Novas, Georgetowns, Louisvilles, and UNLVs of the world a shot in the 80's/early 90s.
Current-day Villanova is the exception that proves the rule. Gonzaga is knocking on the door, but I would not give them much of a chance in a normal year (i.e. fans in the stands). Hopefully UConn can get back to that level as well.
I trust in Hurley, by the way.
