The problem with markets for the AAC is that no school in the AAC is large enough/important enough to deliver a market outside of UConn. Houston and SMU don't really move the needle in the state of Texas. Top recruits don't go to Houston or SMU, so other AAC schools certainly can't expect to come in and grab 4 or 5 star recruits from the state when Houston and SMU can't even do that. Same with UCF and USF in Florida. There is no way the AAC would ever have its own TV channel, so those larger markets can't be utilized for a cable channel. The only market benefit would be for the national ESPN contract, and that isn't necessarily a great benefit. It's good in the sense that ESPN will pay more for Houston and SMU and the little they bring the Dallas and Houston markets than it would for Marshall or Middle Tennessee, which have no major markets at all.
The old Conference USA never was considered anything major, so why would it be so now as the AAC? UConn replaces Louisville. That is more or less the only difference. Temple is on the level of the old Conference USA. Everyone else is the old Conference USA.
How many of those teams have ever had a top 5 finish to even have a shot at the current 4 team playoff? I think a 2 loss team in every Power 5 conference would be considered first before an undefeated AAC team. I don't think an AAC team will ever sniff the playoffs, even if they do expand to 8 teams. Ten years ago, would anyone have said a Conference USA team has a shot at the playoffs if the playoffs existed? Of course not.
UConn is just stuck right now, whether its fair or not. I don't think its permanent. However, UConn needs to take care of business to ensure it gets out. I'm sure Cincinnati and others are thinking the same thing and are trying to position themselves to get their ticket out, so it can't be a forgone conclusion that UConn is next in line necessarily. You have to work at it to make sure it happens and don't just assume it will happen.
