He made more putts in his 20s and early 30s than Ernie Davis Vijay made in their careers combined. (Only being slightly hyperbolic.) It is unreasonable and greedy to think it could keep going that way forever.
At Evnroll we engineer larger spaces between the grooves in the middle of the putterface and smaller ones in the heel and toe sections to equalize speed on all strikes. Without this variance in groove design the ball would travel different distances depending on where you made contact across the face. Trust me — you don’t want that.
Who knows? It’s plausible given all my friends in their 40s are now getting glasses and Lasik and using the flashlight on their phone to see menus better. Tiger’s stroke still looks pure so since he’s not making any putts and has often been iffy on the greens this year you have to start wondering about other causes.
