Why UFC don't Have a Kung fu Expert Player?
Because Martial Arts have a component that is missing in UFC..... Art. They aren't interested in the venue.
Because Kung Fu doesn't really work when your tackled.
I think the UFC do not have a Kung Fu expert player because they are not allowed to train the Kung Fu system. Another reason could be that the UFC do not have experts that would be able to train the players.
that's why its mixed mma im sure they use some type of kung fu but like bruce lee said never be focused on one art , expandyour mind, learn a multitude of different styles and you will be invincible
