I see your point. He was definitely nearly impossible with the lead in his prime - however, the times he absolutely had to make a putt or shot, he came through.....twice in majors to force a play-off, President's Cup in South Africa. His final round at the '19 Masters was clutch too, but that is his only major championship victory where he had to come back in the final round.
I was thinking also along the lines of how he approached the game and his craft - and now with just trying to be able to compete - to me, much like Rafa Nadal and Novak Djokovic in some ways.
