He made so much for the sport, his impact was so huge, his fighting style, his dominance, his magic, memorable winnings, memorable performances, so many years undefeated on top, so many title defenses, so much impact inside and outside the cage.. all of this is so great that isn't a couple of defeats in the final of his career that will change anything about his spot on the top 3 of all time to me.
