The author is "debunking" somehting Joe Lewis said. While I agree that Frank Shamrock's talent in no way protects you just by training like him, who would you rather aspire to be (in a fight) Frank Shamrock or Phil Elmore? It seems that the basic assumption of a lot of RBSD folks is that you will never be good enough to fight like a pro MMA fighter so training like them will not help YOU. How is that leap of logic tolerated? In what other field is the training of the elite considered ineffective?
"What major flaws does anyone detect rendering pro fighters helpless or at a disadvantage in a street fight when observing sport fighters, the likes of Mike Tyson or Frank Shamrock and others?"
We are not talking about Frank Shamrock or Mike Tyson, but the average person who studies and trains in martial arts and/or self defense. Unless they have the skills of a Mike Tyson or Frank Shamrock, what those two can do against a streetfighter is largely irrelevant.
