Jon Jones said after the Belfort fight that he never focused on BJJ. He just concentrated on wrestling and muy thai. Then he said he was going to focus on BJJ after he almost got caught in the armbar. But my question is... is BJJ knowledge even necessary in MMA? If a solid wrestler/ muy thai practitioner can come in there and win all of his fights without BJJ knowledge, is BJJ knowledge even important in MMA? Great wrestlers seem to handle BJJ practitioners quite well, which makes sense because it is a form of grappling.
