Well....It's a little embarassing....but....ah....I'm trying to emulate RJJ

Not with the low hands and the reliance on reflexes for defense, but offensively anyway.
I sparred last night and although only one of the 5 guys I sparred was quality I felt it worked for me. I was rising up the right hand and throwing it sraight and I felt great.
I need to increase my speed obviously to use this style.
So I've got a dual question;
1. Is there a fighter that you aspired to be and trained like? 2. What steps did you take to train like him?
