@OskieSD is right. The athletics department at Northwestern has had problems. Wasn't the coach they hired from Army let go because of a "toxic environment"? And the football team had hazing issues. Your son should definitely try to ask the current players about the new coach and culture.

Your son should also be comfortable with the quarter system there. I think most of the baseball team takes classes during part of the summer to free up time during the season. It is a beautiful campus, and the new baseball facility there looked awesome when my son toured a few years ago.
Dartmouth was 3 and 38 last year. . . .Their coach has been there for 34 years. It does have a great business school though.
