Can anyone think of any tour player who ARCHED the left wrist at the transition who wasn't one of the best ball-strikers?
Cal, Trevino, Watson, Lehman, Claude Harmon, Joe Durant,....we could go on and on.
And likewise, I bet if we look at the guys at the bottom of the ball-striking stats, we won't find the bow nearly as often.
Well...Hogan, Moe, Knudson, Nelson, Boros, Venturi had the wrist rather cupped. I put these names against yours ANY moment. It just proves that it does not matter in macroscale and this is not an useful common denominator.
