Basketball of any kind means nothing in conference realignment decisions. It's only about football because that's where all the money is made.
That said, UCONN is the other piece of the NYC media market, which includes Fairfield County. For football, Penn State, Syracuse, Rutgers and UCONN share it, probably in that order. The overall problem is NYC is not a major college FB market. It doesn't have that many college sports fans that ID themselves with football. As an example, Atlanta, GA, a much smaller metro area, has about the same number of folks that ID themselves as college football fans as the entire NYC metro media market.
