Overall excellent analysis. However, I question if there would be enough yes votes from the six Ivys, Clarkson, SLU, Union, Colgate and RPI to ever admit Holy Cross or any Catholic institution for that matter. My best guess would instead be RIT who may be paired up as travel partners with Colgate. The travel time between RIT and Colgate is actually less than the present travel time between the Q and Princeton. Of course, I am assuming RIT is also an opt out.
No, SLU is not Catholic. It is not named after a saint. It is named after a river!!! Also, despite being a Catholic heavy MACC member for most of their sports, the Q is not Catholic either as far as I know.
Am I really hinting that the luminaries who luminate (a Clyde Frazier saying) institutions that make up ECAC Hockey look down at Catholic institutions with utter disdain and contempt??? YEP!!!
