 The first thing you would do, well, I was a pulling guard, so I used to wear these arm pads. So when I was chasing linebackers, the first thing I would do was I'd give them a little shot with my forearm up under their chin, and their head would go snapping back. And one of my teammates, Cornell Burbidge, used to say, he said, boy, you look dirty. And I said, no, I'm not dirty. I said, I'm just going to give them a little shot to the chin real quick. And so that's how it kind of started. He started calling me Dirty D. And then it just kind of stuck with me.
