But he s not a Nak Muay, dude. I mean a fighter fightingunder MT rules does not make one a MT fighter.
OK forget the ugly comment because that is purely subjective but no he does not fight like other Muay Mats. Wangchanoi, Veeraphol, Lakhin for example fight nothing like Dekkers. It is not about what you employ but the whole rythm of fighting, the distance management, everything. No Thai fights like Dekkers. Muay Thai is more than just a ruleset, you know.
BTW it makes it even more impressive in a way, that he was able to prevail so often against Thais under their rule but by using a very limited / specialised weapon set. Dany Bill for example IS a MT fighter. He also came from Europe BUT adopted a slick femeur style at jocky gym. He said it himself that he wanted to learn this style from the best at this style. At the same time isn't it notorious that Dekkers was convinced about his Dutch style and DGAF about expanding his knowledge?
So yes absolutely, because of all the above. Dekkers was never a MT fighter. He was a Dutch style kickboxer who prevailed in a ruleset that wasn't his.
