John Cullum:
1) #18 has never been "holdable" from the rough under any conditions - for members at 405 yards, previous championships at 440+ or the '05 Am at 500+.
2) The green has always been (including last week), "holdable" from the fairway with any resonably lofted shot from about 200 yards OR you can bounce the ball on as Hogan did with his 1 iron in '50. That was do-able last week as the fairway was not watered in front.
I saw some pretty impressive soft 3 woods from 220+ in both the '71 and '81 U.S. Open that had that "butterfly with sore feet" thing when they landed.
If you're a talented ball striker and long enough off the tee, that green is eminently fair - not easy but definitely not unfair.
Thus, is the 250+ hitter at a disadvantage to the 300+ hitter on that hole given the demands of the 2nd shot? You bet, but that's not unusual on most any long hole, I think.
Also, it is MUCH easier to chip back to the hole from over that green - even from the rough - than from the fairway in front. Missing long is way better than being short so I'm guessing that some of the shots you saw were more-or-less intentional. Either that, or the players you saw didn't have the right shot in their bag, so to speak. How many college-age bombers have you seen that have learned to hit a high soft middle or long iron?
3) Not that it changes this discussion, but the hole location was very much in the front on Saturday - did you not see Dillon Dougherty's shot that hit the flagstick (basketstick?) and won his semi-final match?
