Machida's particular striking style has proven to be very difficult both from an offensive and defensive perspective. He is very talented and it will be interesting to see how the rest of the LHW div adjusts. Sooner or later someone will figure out a good way to counter his style. Karate in the past hasn't had much influence in MMA b/c it has little cross over ability. This is true of many of the traditional martial arts. Lyoto has really shown to a true Mixed Martial Artist by adapting the Karate stand and strikes to the MMA game.
