Old video, put that boxer in the Octagon with JDS and expect a very different fight.
You can't possibly use traditional boxing in MMA and win fights consistently, 'tis the reason we watch MMA, because no single martial art works on its own against all other martial arts.
People bang on about the boxing of JDS, Diaz Bros, Anderson Silva etc, and these guys would be great boxers if they specialized in it. But when their hands win them a fight, it is not boxing, its being a good enough MMA fighter to the point that opponents have to play their preferred game.
JDS is not a boxer.
