Assuming the two examples above are accurate, you can add any firm fast links..
Except in all three cases driving irons, 3 woods, hybrids and Senior Tour golfers with drivers(Watson at Turnberry) make them more susceptible to low scoring, by allowing more players to be in play and potentially "on"
i.e. Watson can hit his driver where 30 year olds are forced to hit long irons to the same spot.
Simply more players in the game when much of the field is reduced to less than driver on many/most holes.
Look no farther than the barrage of 63's yesterday and the tightly bunched field.
Hard to separate when more people are in position off the tee due to far less separation of skill drivers.
You want to find out who's a great driver, let 'em hit driver....and to do do that it takes either an incredibly clever design,a silly setup, an accident of technology(Colonial-just fly it over previously shot shaping required doglegs) or a really long modern slog of 8000 plus yards...
many of our discussions start with architectural "intent"
That ship sailed on many of our classic courses years ago for elites-a shame, because many of those courses were designed to test elites, yet were playable for the rest due to less substantial scale differences
We can all say "who cares about the PGA Tour", but maybe the PGA Tour player or elite am would like to face challenges such as Hogan, Nicklaus and even early Woods faced and overcame, and separated themselves from the field with.
Not just how to hit one of 4-5 wedges with precise distance control.
