Why no BC “for obvious reasons?” Sacred Heart and Mercyhurst are both Catholic institutions and they will be playing in the tournament next season. PC has played there as well. In fact, I just noticed that P.C. has an overseas study program in Belfast.
As for Quinnipiac to HE, my understanding is they are very happy in the ECAC and have no desire to leave. They are positioned to be competitive every season and, as a school that has enhanced its stature tremendously in the last 25 years, they like the association with the Ivies and other selective privates. In particular, I don’t think they ever dreamed of playing rivalry games with Yale and it has come to pass (of course, for the Elis it will never match Yale v Harvard or Cornell, but the energy in the Whale or the TD center is definitely up for the Whitney Street rivalry). I have no doubt they’d do well in HE and it would be a good relationship, but they are already getting what they want and need in the ECAC.
