There's rule changes every year. I do wish, however, that the NFL did have a voice from the players' side, whether it's our players' union president, or team captains, or our executive committee on the players' side. Because we're the guys that realize the risk; we're the guys on the field.

When people say that you kind of just get - you know, just feel like a little buzzed or dazed or had your bell rung - they consider that a concussion. I wouldn't. But if that is considered a concussion, I would say any football player at least records 50 to 100 in the course of a year.

Our sport is not made for anybody to be able to play it, especially at the NFL level, so there's obviously some risk that we all take knowingly.
