I have the utmost respect for the Gracies, especially Rickson. Granted, I think some of their comments are distasteful, arrogant, and offensive, but I respect them for what they've done to promote MMA and how they've gone about popularizing BJJ.
As for a previous comment sayings Rickson is a coward for not competing in BJJ anymore, I say that he has little left to prove. Some of the best MMA guys and grapplers in the world have attested to his brilliance on the mat and his uniqueness as a person. I like to believe much of his inactivity in competition stems from the passing of his eldest son, Rockson, and I can understand why he wouldn't. Lastly, I think he very much embodies what it means to be a traditional martial artists. He is one of those few people who has really dedicated himself to understanding his martial art and has truly become a master at it and, for that, I respect him more than just about anyone else.
