That's a pretty ignorant statement based on a blatant piece of propaganda.
And before you flap at me saying that, I'm personal friends with the leading researcher in the field of CTE in football and have watched numerous videos of my idols brains being dissected. I know exactly what CTE is and I played the game, winning a European championship and was in the mix for a roster spot in NFL Europe before it closed. I've nerve damage due to playing. I coached in Europe and had a stint in a US NCAA Div 1 team. I was a coach educator responsible for instilling player safety into coaches across the world. So I get it.
But the sport is like no other. It's highly skilled at a lightning pace and is as close to actual combat as you'll get outside of an octagon.
You want to know why I'd have my kid play? Because I want him to hold his head high. Too many kids in life these days aren't challenged. We live in a world where it's not okay for a kid to play on the road and scrape his knee. Kids need to be challenged, to fall, to get hit.
To be totally honest I've a huge problem with how CTE is being addressed. The answer isn't to grandstand on tv and take out a player. The solution is to limit contact in practise. It's the tens of thousands of head bumps gotten in 2 a day practices for a decade that are causing the injuries, not a solitary hit when someone is a grown adult. If kids were coached safely and correctly, then this issue could be extremely reduced. But there's 100's of coaches doing things the old "water is for wimps" way and that's what has made this a crisis.
