He starts out OK with zeroing out wristcock and #3 accum while HITTING some punch shots. It's all downhill from there. It's one thing to give the bad advice of throwing the club down from the top with the arms(#4 throwaway), but to do it along with wristcock throwaway makes it even worse.
Anyone who takes this advice will have to overaccelerate the left wrist to keep the left wrist flat and avoid flipping. Without a hip slide preceding the arm movement, the player will constantly be on the edge of hitting fat.
It sounds as if he had been listening to Jimmy "No Angles" Ballard when he makes his "anti-drag" comments and says it leads to hitting the ball to the right. And also it sounds as if he had been listening to Croker.
