All I know. There is now proven science that shows repeated head blows/concussions causes brain injury later in life. And, now with them starting these tackle programs younger and younger, about time someone wised up. And, regards to this year around (IE: Friday Night Tykes) youth football programs, that will be another good place to regulate. Just imagine all the head blows today's youth are sustaining over how many those they detected with brain injury from the NFL, that had donated their brain for research. I'm not totally against youth tackling leagues, but---I am against year around leagues of any sport. Too much, without recovery IMO.
