I definitely agree about the future of youth football being flag. There's just more and more evidence that the youth brain is particularly susceptible to the injury - thin necks, big heads. They're not as coordinated; they're not as skillful. For many reasons, I think the wave of the future is flag football for youth.

I was born with football - my brothers, my dad. I played football when I was a kid. I mean, you know, it was part of life. It's a part of growing up. It's - you know, it's a way of life.

My son was a goalkeeper in soccer, and he luckily never had much head trauma. He never had any concussions or anything. I really wanted him to play football, but now I'm thankful he didn't.

The overwhelming evidence is that trauma is a major factor in CTE.
