He doesn't know what he's talking about, just like DJ.
Both advocate snapping the wrist.
Photos and vids prove their both wrong.
They are good/great players. They are poor analyists of their technique.
Good post. many pro athletes don't really know about technique and act instinctively. they do have strong believes of course and not just play somehow (anyone would say I bend my knees and turn my shoulders) but they usually don't know much about the details. I'm pretty sure federer doesn't know a lot pronation, stretch shortening cycle or the kinematic chain.
the same is true for baseball players. any coach till recently teaches to swing down and get extended. however slow motion of high level players showed that they actually slightly uppercut and hit the ball with bent arms.
but if you ask A-rod, pujols or bonds what they do anyone of them says he swings down. a few years ago they showed bonds a video and he was really surprised he swung up because he had a strong belief that he would swing down.
you don't need to understand the swing when you have the correct FEEL but as a coach some physics understanding certainly is not a bad idea.
