As a youth tackle football coach, for 6-8 year olds, I have to chime in here. You guys are dead on that there's really no reason for kids this age to be playing tackle football. My son plays, and I really wish there was another way available (there was flag, and may be next year but it was so informal and the same 2-3 teams played each other every week). I coach to essentially keep an eye on him and make sure he's being treated fairly and he's being safe. I can't vouch for other teams in other cities/states and in other organizations, but the organization that we play/coach in has not had a confirmed head injury in the last 5 years. This is me and my son's 2nd year being involved, but the only head injury in the last 5 years was a player and his parents saying he had a concussion but never got him checked out for one apparently. But anyway, as coaches we definitely harp on tackling form and teach the kids the right way to tackle. 95% of the contact we have in practice is with pads, handheld by the coaches or on tackling/blocking "dummies". Including, these which teach the kids the "wrap and roll" technique rather than trying to destroy another kid with your shoulder or helmet. http://www.fisherathletic.com/images/Football/TackleWheels/tw-group-web.jpg All the coaches have to take classes to know how to teach this technique and how to spot a concussion....every year. Also, it's worth pointing out that helmet to helmet hits aren't typically the cause of head injuries. Helmet hits cause NECK injuries (AKA whiplash type of things). Head injuries are mostly caused by heads hitting other places on someone else's body or by being slammed on the ground. It's really not a huge risk for head injury in the grand scheme of things at the youth level. There are weight limits and most teams will communicate before the game to try to match up their little guys on the field when everyone is required to play 5 plays. That being said, there's really no logical reason for that risk to be more than 0 for a 6-year old. There's simply no benefit to the individual kid and the only benefit to the organization is having a group of kids that get to the HS level and have a ton of experience playing together. Of course, even then that only happens if the kids A) stay together in the same school district and B) kids stay generally the same AKA big kids stay big and form an OL, fast kids stay fast and are the QB/RBs/WRs. Maybe I'm a hypocrite for letting my son play, but this is something he wants to do and I have talked to him about the risks, though at 6 last year I'm sure he doesn't understand....hence why I'm with him at practice every day.
