Anyone that played football has seen "Stars" or "Glitter". Concussions happen, but your son would have a very good piece of "Headgear" on. Today's technology is unreal, and will be even better as he grows up. I have heard this same sentiment from other former athletes. Football is a great contact sport, and needs to be taught better at the youth level. Guys like you need to step up and coach, and teach kids the proper fundamentals of "Head Placement" on tackles and proper form. Soccer is the sport that leads in concussions. Have fun watching him grow, and hopefully he is a football player one day.
