There isn't one for college basketball or football. There is a fanatic State following for UConn football and basketball, and a surprising national following as well in basketball. National recruiting proves that. BC at best has a few alumni fans.
Well, there may be a reason for there haven't been many great teams in the NE area. NYC doesn't have one, and the last thing you'd do as a NYer would be to root for a Boston team.
Similarly, CT residents who are Mets/Yankees fan aren't going to start pulling for BC. I think, in both the state of CT and in NE as a whole, there is more of a market-share to be grabbed since there just aren't enough teams for the population.
I'm a fair-weather football fan. I watched the clinching game last year and the OU game. I very rarely watch. I'd watch a UConn-BC, UConn-FSU, UConn-VT, UConn-Miami, UConn-Maryland game. All of them hold intrinsic interest to me as an only casual fan. That would likely make me care more about UConn-Syracuse/UConn-Rutgers.
I can't be alone in that.
You're not. For all the talk about BC's "irrelevance" in the Boston market, the football team has a full two pages in the Globe and Herald every weekend. Plus a weekly TV show. Basketball? Only when they're winning. Hockey does get some press, with several Mass schools being good. It's not a college sports town or region. Too many professional options.
Here's why I think BC would probably be in favor of adding UConn. The Boston media tries to play up the ACC, and Boston fans feel completely disconnected from it. Nobody gives a crap about G-Tech playing NC State. But put UConn, Syracuse and Pitt in the mix and that would probably change. Interest in the ACC as a whole would go up, as New England would be more completely connected to it.
