I was frankly shocked to hear this; no reason for it, and embarrassing. It tarnished for me what was an otherwise magnificent exhibition of fan support.
I agree Yaledoc, although there is some context that I learned from my '90s era son-in-law. The Harvard Sucks cheer is not directed at Harvard (except at The Game, of course). It is traditionally directed at Princeton as a backhanded way of denying true rivalry. So, by analogy, the Harvard Sucks chant was actually directed at Quinnipiac, for daring to presume rivalry. I've tried to explain to students of the last 15 years that the cuteness of this wore off a decade ago, to no avail.
So here's a Yale fan looking forward to coming up many more times to Bright and seeing a true rivalry. (Last there for the Saturday playoff loss last year.).
