It's OT and it's definitely not infallible but every now and again you see someone wrap their hands around a golf club and BOOM--you can just see the golf in their bones.
It's sort of like how you could just see music in Louis Armstrong's upper lip and when he put the trumpet to his lips.
I've seen that in my life in the golf grip of Hogan, Palmer, Armour, Glenna Collett Vare and Ben Crenshaw (and actually Buddy Marucci, of all people).
Ben Crenshaw's right thumb alone when he places it on a golf club just screams GOLF!
