As BCI points out, it appears Holy Cross wants to join Hockey East. There are lots of hurdles to clear, but if the Crusaders put together a solid proposal, BC needs to be their biggest advocate.
Even though the Holy Cross-BC rivalry doesn't mean much to any BC fan born after 1970, baby steps towards rebuilding it are good for BC. We are headed towards a time of uncertainty for college sports. Paying players, breaking off from the NCAA, and challenges to Title IX are all in play. Given that BC is proudly anti-athletic payment, I could see a situation where our leadership decides to de-emphasizes sports (especially if the Power 5 really starts up player salaries). However, if our historic rival is moving towards big-time sports (like Football and Hockey), it will put pressure on BC. Why would BC give up the marketing and community advantage that sports brings just when Holy Cross is embracing it? Holy Cross learned their lesson when they decided against the Big East basketball and gave up athletic scholarships.
I know that Holy Cross joining Hockey East is not the same as the Crusaders joining the Big Ten (or even something like the Conference USA), but it is a good first step. And even if it doesn't generate huge athletic momentum for them or start an athletic renaissance for BC and Holy Cross, it would still be good to play them more often. Their return to big-time sports is also a good reminder of what we did right over the years.
