At random I took videos of 10 guys chipping at the practice area, whose handicap I judged to be greater than 10.
I then watched PGA Tour golf and confirmed something I already knew.
On short game shots good players have lots of wrist hinge and very little arm swing going back…and have very little wrist movement and accelerating arms (trail arm especially) going through.
Bad golfers have very little wrist hinge and lots of arm swing on way back and very sloppy wrists and very little arm acceleration (trail arm especially) on the way through.
Every bad short game shot I see from good players lacks wrist hinge or an accelerating trial arm….or both.
