I'm a Yale alum and I'm fine with it as a one-off. The encrustation of tradition around The Game, and Ivy League football, and the Ivy League in general, could use a shot of novelty now and then.
As I tell other alums who are too critical of the Old Eli stuff, you're having it both ways, in that you want to associate yourself with the prestige of the Yale name, and simultaneously distance yourself from/make fun of the stuffy, exclusionary, pompous WASP old money culture that spawned it. So yes, the traditions should be respected.
But also, FFS, it's Ivy League football. I think the quality has improved over the last 5-10 years, but if 15-yard punts and QB draws on third-and-14 are your thing then you're all set. I once dated a UCLA alum and big football fan and she was excited to attend her first Game (which of course was on the same day as UCLA-USC). After the first two series she looked at me stricken and said "this is football?"
Tradition aside, it's also the (extremely) rare circumstance where the amenities of Fenway (food, bathrooms, creature comforts generally) are an upgrade over the other venues.
Yale and Harvard hockey played at MSG a couple of years ago. I went to that and it was fun. The earth kept spinning.
