You are assuming they haven’t been approached (they have heard from conferences including the Big East I have heard) and are looking to make a move, and want to come to the Big East. They have been playing it coy waiting to see what would be the best spot for them and I don’t believe they are convinced yet the BE is it. Again they do not have to do anything right now. They know out of the “basketball only” schools, they are one of if not the most attractive (Villanova would be the other but they are in a stong conference already).
Mark Few was quoted the last realignment that it wasn’t the Zags that had a problem with travel. The implication at the time was that a good east coast conference didn’t want to have to travel west. At the time it was assumed to be the big east (around the time UConn came back in).
