Some of you talk as if talent grows on trees.
Talent is not "competence". The latter is much more common. I've never played a professionally-designed golf course and come away thinking that the architect was incompetent.
I'm convinced that all working professionals know more about the game and its strategies and design possibilities/options and routing than I ever will. But that's not talent.
It's talent - not the site, the client, the budget, the environmental restrictions, the intended market, or even the intentions -- that separates the competently-designed 3s and 4s (that I've played dozens of) from the very good 6s and 7s (of which I've only played a very few).
The talent to shape intriguing, exhilarating, varied, challenging, playable and strategically-meaningful greens hole after hole after hole.
The talent to juggle in the mind's eye several potential routings, each with its own pros and cons, and emerge with a flowing routing that highlights the site's strengths, hides its weaknesses, and provides a consistently good field of play.
And the talent to imbue that whole field of play with a pleasing aesthetic that is not obvious/eye candy but instead a subtler melding of many qualities: e.g. the blending away of fairway lines, the connecting of greens to their surrounds.
Talking about whether there "should" be more/less "3s" as if we "could have" more 6s and 7s just by wishing them into existence seems to ignore the nature/reality of talent.
Some have more talent, and some have less -- and most of us have less of it than we'd like to believe. If someone ever manages to bottle a talent-pill that I can take twice a day, please let me know.
