Re: Gary Player, I suspect that he will have an outside chance to shoot his age at the Masters, and that would be a wonderful accomplishment. I don't know that Nicklaus will have that opportunity. BTW, has that ever been done there or at any regular tour event?
Re: Jack Nicklaus, it is an overwhelming concensus here that the man is anything but as asshole. I've been around him a number of times and am acquainted with people who've worked with him and know him very well. The only negative thing I've ever heard about Jack is that he can be a bit stubborn, and, at times, he can razz his friends pretty hard.
More commonly, he is described as a very loyal friend and family man, at times hard on himself, and as a person who fully understands what golf has done for him and what his responsibilities are to the game.
Past critics such as Lanny Wadtkins and others from that era can try to knock the Golden Bear down with snide comments about him being a pompous know-it-all-Carnack, but who would anyone rather meet or have a beer with, Jack Nicklaus or Lanny Wadtkins. I remember once hitting a good tee shot in front of a large group of Oriental engineering recruits at a company course, and while I could not make out much of what they said as they clapped, I did pick-out "Jack Nicklaus" with no mention of "Lanny" or "Wadtkins".
And when other lesser players complained about "foreigners" such as Gary Players coming in and "looting" the PGA Tour, it was Nicklaus who defended a system of meritrocacy as opposed to one of barriers to foster mediocracy. Had Nicklaus been able to be a benign dictator for the tour, we would not have the blandness and closed nature of the existing exempt tour and the technology issue, particularly the ball, would have been addressed long ago.
Finally, being that this is an architecture website, I would like to know which architect has done more successful, quality courses than Jack Nicklaus without any major brain-farts in the mix. The last three Nicklaus courses I've played, Las Campana-Sunset, Cimarron Hills, and Sherwood are not short of outstanding.
Arnie may be the King and certainly the most beloved. But Nicklaus is clearly in a class by himself, and arguably, among the most respected athletes in any sport. I wouldn't count Tiger out, but he does have a little ways to go, and perhaps his large intimidation advantage has been diminished.
