To me, the question of who we want to play is influenced by what our goal is. If we want to win the ECAC's and we think that Cornell is the bigger possible stumbling block, then wouldn't it make sense to play them in a 2 out of 3 instead of a single winner take all where anything can happen? That to me would seem like an argument to play them in the quarterfinals. If instead, our goal is to make it to the NCAA's, then a sweep in the quarters is the best path for that, and then Brown would be preferred (I am basing this on other's opinions - I am indifferent myself).
Therefore I guess it all depends on your view in life... if you are a glass half full person, either outcome gives us something to be happy about (better chance at the NCAA or a fairer competition (2 of 3) against a potentially tougher opponent).
