From the time I was first able to walk, all I ever wanted to do was tackle people. I tried out for my first team when I was five. I didn't make it because it was all seven and eight year old boys. When I got on a team two years later, I was starting by the third game. Even at a young age I had a deal with my Mom. If I ever got hurt bad, and had to be carted off the field, she was to stay in the stands until I got checked out. I always knew the risks involved and I accepted them.
If I ever had a son, and he showed that kind of passion for the game, hell yes I would let him play. He would know the risks and make his own decision just like I did. As bad as my neck, right shoulder and both knees are now, I wouldn't trade it for anything.
