My U-tube name = Imperfect Golfer. That means that my visual demonstrations are imperfect. However, that doesn't mean that my understanding, or written descriptions, are imperfect.
I wrote regarding this next video-: "Note that Scott has maintained a bent right wrist (which is called a frozen right wrist) throughout his entire swing - backswing, downswing, followthrough and finish - and that he doesn't change the degree of right wrist bend at any time point throughout the swing."
