I remember you posting something but I recall it was a BJJ guy and a boxer???
Well I would get in a fight with the WKF world kumite champion if that's all he has done he'd at least break his arm if he hit me! Ehh sarcasm aside yes obviously any training is better than none.... But ''some'' training that isn't all that effective for self defense can create a dangerous delusion in a practitioner that they are trained for something they aren't (if that makes any sense)
