Getting those next five majors to best Jack Nicklaus’s record won’t be easy for a suddenly human Tiger Woods. First, he has a bum knee. Second, he’s getting older, and a certain amount of decline is inevitable. For many players, the first thing to go is the putting, which is what killed Woods yesterday. Third, watching an unknown Korean do to Tiger what he usually does to other players in the closing round-make him blink-has got to be emboldening to guys who have been cringing in Tiger’s shadow for years. Like sharks, they may smell blood in the water. No, Tiger is far from washed up, but he’s definitely beatable. And his job just got a whole lot harder.
