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 greatest hope is that we learn how trauma induces neurodegeneration in susceptible individuals.

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.

Sometimes you have tough moments, sometimes good moments, and this is normal in football.

In sports, the confluence of the 1989 Oakland vs. San Francisco World Series and the Loma Prieta earthquake notwithstanding, the earth rarely moves.

I remember running at school sports day, and I would win everything, but I wasn't a super athlete or a superstar at high school.

Some people are tired of hearing me tweet because they want me to stick to football but I like to use social media like I was a regular guy because I think I am.
