We have seen MMA change quite a bit over the years. BJJ did wonder for a while then some other techniques took over. In the last 4-5 years, which technique do you see as an absolute must to master to a high degree in order for a fighter to reach the top ten or even the top? That's among Muy Tai, wrestling, boxing and BJJ. You can throw in some less popular ones like judo or Tae Kwon Do who seem to get the job done for several dudes. Of those techniques, which one do you think is the "fastest" to learn at a proficient level if you are a "late starter" and which fighter did you see add a new technique they were not associated with and that is getting great results within a relatively short amount of time (a few years)? One of my choices would be TJ Grant. He had a great grappling background but his trips to Thailand are paying off in the sense that his Muy Thai is clearly catching some guys by surprise these days. Another one would be Vitor. I am not sure under which category his kicks would fall as so many disciplines use kicks but his "new" kicking game is now something the other guys have to watch for big time. What's your "must have" tech and which fighter impressed you the most with a technique they really started to master in the last few years?
