There is nothing "fantasy" about the existance of ground fighting and grappling in the TCMAs, and that is the point.
If I had said that there were effective low kicks in Wing Chun, would you base the validity of that statement on wether I could use those kicks or not?
My Wing Chun sifu is in South America. If you are planning to fly over there for a challenge match, I would suggest that you polish up your skills to first be able to survive an anarmed fight with the fourteen year old gang members, before you go on to challenge martial arts instructors....LOL,LOL,LOL!
If he did cross train, then I would hazard a guess that he did in another TCMA, which would have been
relevant to his core style. He would also have
understood his core art before going on to improve it!
Yes, very true, and may your "journey" to the MMA forum be a fruitful one.
