"I'm known as the guy that I am on the field," Harrison said. "That's not really the person that I am -- mean, crazy, blah, blah, blah, you know. I play a game that is a violent game, and you can't go out there with a smile on your face and do your job. It's just not possible. I've never seen somebody tackle somebody with a smile on their face. That's just part of the game. Outside of the game, I'm me. I'm laid back. I joke. I laugh. I play with my kids."
