Have now realized that in my previous I failed to give special mention to David Duval. Apart from any other golfer, Duval, if for only a brief time, had his own special kind of "Right Stuff". He won the 1999 Players Championship and 10 other PGA Tour events within a two-year period from October 1997 to October 1999, then later added two more wins, including the 2001 Open Championship at Royal Lytham & St. Annes. In addition, he was the 1998 Leading Money Winner, wrested the #1 Ranking from Tiger Woods at least twice, and had success in team competitions such as the Ryder Cup, Presidents Cup and World Cup.
When Duval was on top of his game, he was a force to be reckoned with. When interviewed on David Feherty's Golf Channel show, Duval more or less said that he wanted to compete, wanted to win. I believe it is safe to say that he certainly had all the right motivations to have a phenomenally successful career, taking on all challengers, whoever they might have been.
Unfortunately, as we all know, that intense desire quickly left Duval not long after his 2001 Open Championship win, and his career took a steep nosedive. Fortunately and most thankfully, his personal life has became a happy one, and he is at peace with himself.--but we are left wondering "what might have been!!".
