Tim,
Thanks for the answer. I feel there are probably a few ways that a course can be top 10 from 60 yards and in but not top 100 overall, but are probably unlikely in practice because any architect team good enough to build world class greens and surrounds would probably know to avoid the pitfalls:
1. Tee shots that are too difficult for most golfers--forced carries, narrow fairways or tree canopies, excessive hazard use, etc. that take the focus away from positioning one's ball with the approach in mind to just trying to survive the tee shot. Great greens are fun, but if you have to get up and down for bogey or worse all day, a little luster is taken off the course as a whole.
2. Tee shots that are too repetitive or overly favor one type of shot; lack of variety--the greens and surrounds can be world class, but if the player is asked to play the same tee shot over and over, or if the hole distances are too similar, then that may be enough of a negative to take it out of top 100 consideration.
3. A course built on a property that is so restrictive that it forces a severely "unbalanced" routing, something like a par 67, or 6 or 7 par 3's, or something like that--even world class greens (or holes for that matter) probably wouldn't win enough people over to overcome their bias against such routings.
4. Tee shots that lack interest or challenge--if they truly lack interest or challenge for everyone, and the tee shot is just a formality to get to the approach, then I can see where it could fall out of the top 100. If it truly lacks interest or challenge for just the most skilled players, and that was its only drawback, then it probably would have to stay in.
With that in mind, then, my hunch is that David's statement probably isn't true to the letter, but then again I don't think he meant his comments to be taken to the letter.
I think he meant to say that there isn't enough tee shot interest and challenge at RC, for more than just a small subset of players, to keep it in the top 100. I think this may be possible, but until I see the course for myself I'll just have to file it away. I don't agree with the reasoning that just because there are no other courses that are top 10 from 60 and in but outside the top 100, that it's not a possibility.
I'll stay open-minded on this one.
