I'd prefer my kids play baseball, basketball, or something with less contact. I don't know what I'll do or say when/if the time comes if my kids really want to play a heavy contact sport. I'm hoping they will just enjoy sports, stay physically active in some form or fashion, and focus more on studying. I'd prefer they not play a sport highly likely to get their noggin caved in. You can't predict everything, but you can play the odds.
