It is real...but to me there's no art to it. It's just sloppy fighting if you ask me.
Here's what bruce lee himself thought about wrestlers/boxers VS martial artists.^^^^^In the book that Bruce Lee wrote 'The Tao of Jeet Kune Do' he states "most Americans schooled in Boxing and Wrestling could beat any Traditional Martial Artist practicing at the time." Which is what he came to think through experience.
Here's another quote: "A man with one year training in boxing and wrestling can beat any martial artist with 15 years of experience" -Bruce Lee
So do you think Lee is wrong?

When it comes to talking about bruce, it's like talking about Jesus with some people, "he can do anything" and they don't want to hear anyone say anything different.
It's the grandest illusions that die the hardest.
