Roy Jones is a boxer. He is/was unusually fast. Several years ago, a friend of mine was boxing and trying to be like his hero Roy Jones. I told him Roy Jones was an extraordinary athlete with exceptional handspeed, and that he should not copy him. That eventually the person who relies on the exceptional abilities will end up on his back on the canvas. Sure enough Roy Jones ended up getting knocked out, because his style relied on him being faster than his opponent.
As far as marketin, I don’t have a problem with it. What I have a problem with is the over the top, you learn this you can defeat anybody attitude some MA’s use.
