Of course Blackmar is right, but the jury is out on the question of how to deal with this plight. First of all, unless the courses are 7500 yards or some other inhuman length, these robots will play drive-and-pitch all day long. At the U.S. Open at my club last year, they were hitting nine-irons and wedges into our 496 yard dogleg 18th hole (9th in the championship). The new Fazio golf course where they played the Honda is a new wrinkle on the question of how to bedevil the pros. He created Pinehurst-like green complexes with very little square-footage to deal with. Ridiculously undulating greens with impossible hole locations will surely be the next defense to the skill of today's tour players.
The truth is we have now reached a crisis point in golf course design because of the quick leaps encountered in ball and club technology (to say nothing of player fitness and competitiveness of the fields). Soon, courses will either be designed for the regular Joe or just for the tour, because the greens will be too difficult for high handicappers to deal with, regardless of what tees they play from.
Somehow, classic courses like Riviera, Shinnecock, Oak Hill and Olympia Fields have shown that they can be stretched, tightened and made more difficult by adding rough height and green speed, but how long will this be true? I can tell you this based on first-hand knowledge: there is no more room for lengthening Riviera or Olympia.
