I wouldn't do it if there were large number of APO undergrads or in a town where the University is the main business in town (like Slippery Rock, PA), but given then situation, I have more problem with your rooting for the Pats.
OTOH, if the Pats end up playing the Cowboys in the Super Bowl, let us know where in the DC area you will be watching, so we can both root against the Cowboys. (My wife and I live in Montgomery County, MD) (just north of DC for those of you not in DC metro)
