Massey says 1) AAC, 2)MAC, 3)WCC, with hardly a dimes' breadth between them. Which means that if the AAC didn't have UConn, it would be well behind the other two.
Here is where each team from each conference is rated :
AAC: 2, 46, 81, 91, 104, 134, 146, 162, 187, 193, 200, 204
MAC: 33, 41, 62, 77, 90, 112, 117, 141, 181, 205, 216, 223
WCC: 17, 59, 70, 92, 106, 122, 159, 186, 232, 241
If you took UConn out of the list, the remaining AAC teams would be a notch weaker than the corresponding teams from the other conferences all the way down until you get to the last couple bottom-feeders.
Just as a conversation-stimulant, here's the Big East
BE: 10, 20, 36, 53, 68, 78, 80, 84, 88, 137
The bottom team (Xavier) would be a 50-50 team in the AAC.
