I know your not a BJJ guy Phil, but have you ever seen 6 - 10 yr old kids at a big BJJ comp? At my club there are at least 3 that age I can think of, who allready have cauliflower ear \ ears... They get choked unconcious, can't tell me that's good for a growing brain. I've seen one kid ko'd from hitting the mat with his head so hard during a take down, he did'nt move for a full 5 sec at least. Seen torn shoulders, a dislocated elbow, broken collar bones, etc, etc.... But is that o.k because at least their not hitting each other ??? Ref's aren't perfect, they can't stop everything in a kids match, anymore than an adult's. And let me tell ya, those little tornadoes can move! In fairness thou, that's been spread out over a couple of years, unusual to see more than 1 or 2 at any one comp. So....if these girls weren't allowed to make full or any contact with the grey matter, would every one's opinions be different then?
