Idolatry in any form is a setup for disappointment; no one is perfect always. Rickson would be among the first to encourage you to blaze your own trail, before following his. I trained with him while he was still in Torrance, then for a spell in LA, then again in a studio in south Orange County set up by a couple of his students. My thoughts on him? He is one of the nicest guys you'll ever meet...a trait that seems to run constant in masters and champions who don't have chips on their shoulders, and know they know what they know. He trains and competes with intensity, which many have mistaken for attitude. On the contrary, he'll be the first to help you up (after he's choked you out).
Enjoy your training, and listen for the details. One thing that makes Rickson better than many is his grasp of BJJ as an art, and not just a constellation of grappling techniques. Rolling with him, one really gets the feel of the artistry, and not the wrestle. (Read: "This guy owns my butt, and looks good doing it"). They all know the techniques, but they are not all artists.
