I read on wikipedia that in recent years, it has become less popular, but they do not mention why. I understand the philosophy of the art and it seems like Machida and Anderson Silva use similar styles. These are 2 of the best fighters in MMA. Can anyone shed some light on this?
I can't comment on the people you mentioned. What I can say is that White Crane is a good style. BUT, it was never as popular as arts like Goju-ryu, Shotokan, Shito-ryu, and many others. It is curious that Wikipedia would say something like the style is less popular. But then I have always taken what I see on the internet with a grain of salt. Anyone can post any thing they want on the net. That does not make it true.
