"I respect the league trying to better our game and guys like that, maybe he needs to get suspended or taken out of the game completely. I understand. I get it. I was one of those guys. I played defense growing up. I was a headhunter. Even sometimes on the offensive side, I played that way. But with rules in place, you've gotta respect it."
