There aren't ANY good boxers in MMA. If a boxer stays true to real boxing. he will get taken down and tapped out. Once you work on becoming a "well rounded fighter" you are already becoming weaker in your special discipline, no matter what it is. There are no great specialists anymore. You won't survive trying to use only one discipline; Boxing,wrestling,Jui Jitsu,Kickboxing- it doesn't matter. If any of these guys could really box, they would be boxers. Pacquiao makes more money than any MMA fighter, and he doesn't have to sell T-Shirts on the side!
