Putting is not too far from a free throw. Just you and a technique. You're doing something you've done a million times before. But you have to block everybody and everything from your mind. What it gets down to is confidence and pride.
Confidence is based on having done it before.
Tiger's confidence is so high because of his work ethic and his past success. And he performs the way he does in the clutch today because he has such confidence. If he wants to hook it around the damn tree, he'll do it. The rest of us don't have that confidence, or that past success, so when we hook the stupid ball, it hits the tree. Tiger's pride is such that he won't allow himself to be caught off guard.
