For some reason I want to say that Rockson was supposedly truly gifted? He was supposed to be the heir to the throne. And, granted, he was able to have some of the best instruction from the day he was born I think I remember hearing that he was shaping up to be another Gracie prodigy? Don't take this as gospel as it's been a few years now (sheesh, almost a decade) but I thought the word was that Rockson was better than Kron at various age levels in their life (meaning Rockson was better at age 14 than Kron was when he reached 14, and Rockson was better at 18 than Kron was when he got to 18, etc.) Now Rockson died too young to really influence the game and be a force, but if he was better than Kron? And Kron is one of the best in the world? Sheesh, who knows? Then again, it could be another case like Rolls/Rickson where it took the death of one to truly bring out the talent of the other?
