Tiger Woods is playing the best golf of his career (and possibly anyone's career) and he's not getting credit for it because he's not winning huge against a vastly improved field. "Woods of the '90s played against great talent hindered by a lack serious training; today, Woods plays against great talent enhanced by serious training. The slack is largely gone, as is the reasonable expectation of double-digit victory." He's also come back after slumps due to swing tinkering, marriage, and the death of his father.
