Do you think that Tiger is aiming for Hogan plane through impact but his flat left wrist (WITH HIS CURRENT TIGER GRIP) from top/transition does not allow an on plane motion, late release of acc 2/3 and elbow plane?
I think that only someone like Yoda knows the answer. And he probably won't say even if you torture him. But he may point to the problem. I bet his answer would be 1-L; somewhere.
I couldn't say what his Driver Problem is. It's beyond me how a guy can hit a two iron from 235 yard to a tucked pin yet can't hit a fairway with the Driver. But, even his mid irons are off.
I think that Bucket makes a strong case about the #3 and off plane Right Forearm all over the place.
A contributing factor could be the ridiculously diffused sweetspot on that hellish driver, but I would think that he would have had that tweaked out of his handmade driver a long time ago but not out of the Production model. However, he could probably play with a Hockey Stick.
One thing is certain. Tiger ran into a problem that he hasn't solved yet.
