His Putting keeping him Down, like an anchor. I still maintain that this is due to what he did to his wrist, while playing Pick-Up Basketball Game (?) or some other similarly foolish pursuit for a kid with his talent and future within a sport.
I heard that Tiger himself said, Of Rory's Injury: "The Nature of this injury could equate to he will not ever be what he could have been".
Thus far that seems to be accurate. Some Thing has effected his putting.
