LOL! That walrus apparently didn't know that that little guy could kill him in less than a minute if he wanted to. Not only that but break your arm or ankle, just about anything he wanted. The Gracie family is very well known in MMA circles. And Royce--pronounced Hoyce--would about as soon fight on the ground as on his feet.
I'm sure there are people who post here who know more about it than I do but anyone who is into it even a little bit knows the Gracie family. They are pretty famous in MMA circles.
