I wouldn’t classify a group playing broomball or some of the scooter games as ‘sporty.’ My daughter plays club hockey at her school and some of the players couldn’t even skate (and IMO were kind of dangerous to have on the ice) and no one would call them sporty. They were just having fun, trying something new. Schools can have classes to try line dancing or bowling or hiking but one doesn’t have to be particularly athletic.
College is a place to try new things. I don’t think that a 16 year old who has never been in organized sports has to stick to that for the rest of his/her life. Maybe he really would like to be on a kickball team or try an obstacle course to raise money for charity. I think many a college sophomore decides that she really does like drinking wine or attending a party when her parents were on CC saying the student wanted a school without Greek life or parties or sports. Things change. Kids change.
