Ben Saunders won his fights using MMA and not jeet kune do. please show me one example of him using jeet kune do. ive never seen him use stupid **** like sticky punches, trapping or useless TMA kicks; he utilized traditional MMA(ie boxing, muay thai, wrestling and BJJ) to win his fights.
Jeet kune do, wing chun and other gimmick martial arts are TRASH and bruce lee started realizing it later in his life. in his book the tao of jeet kune do he wrote -
""Someone with only a year of training in boxing and wrestling could easily defeat a martial artist of twenty years experience."
--Bruce Lee
in my opinion what we see now in MMA is the vision that bruce lee had for jeet kune do, but he died and it got watered down by garbage, USELESS traditional martial arts.
