I think there's some kind of swearing in between sophomore and junior year there. During the government shutdown/sequestration a few years ago, I remember they almost had to cancel an away game because there was some halt on non-mission critical travel (or something like that) and it applied to the upperclassmen.The Air Force offer is interesting. The services are REAL picky about pre-existing conditions because if they get worse while the guy or gal are in the service they could get stuck cutting a service-related disability check for the rest of the person's life. Maybe they aren't as worried about it in the academies since the cadet is not sworn in until graduation. Seems to me if his knee is good enough for the AF, it should be good enough for NU.
