Lmao Kevin Holland is a terrible MMA fighter and nothing he does in the cage is kung fun based, pay berry is primarily a kick boxer and trained in MMA before becoming a good fighter, dan hardy also practices the MMA system in his fights, and cung lee practices sanda which is basically Chinese kickboxing, trained in wrestling and other useful martial arts and he's obviously learned proper kickboxing in his time fighting. None of what they do is "Kung fu" based. But obviously I'm talking to someone who's still in love with the mystical arts so you win lol carry on shifu
