While I would never wish to see UConn's streak of never losing a regular or post-season conference game in the AAC come to an end, I think it's great if the AAC as a whole gets stronger.
I'd like to see more AAC teams in the tournament, and stronger in-conference competition will only benefit the Huskies.
You can get both your wishes - UCONN CAN go forever without losing a game in the AAC, and the AAC can indeed get stronger! In the old days (Big East), from 1994 thru 2013 (20 years), UCONN lost a grand total of 18 games. They had 9 total years that they were undefeated. I'm betting at least half of those 18 losses were to Notre Dame. Actually I looked it up and I think it is 11 losses to ND. So really, ND was the only team to ever challenge UCONN on any kind of consistent basis.
I hardly think there's a team in the AAC that is poised to challenge UCONN in the next 4-6 years. Can't say "never", but as long as Geno coaches, and the American does not add Baylor, ND, SC, tOSU, Maryland, etc etc, it's doubtful they will ever lose a game in the conference... Heck... the way they are going now, and the way Geno's recruiting, he may never lose a game out of conference either!
