I don't agree with you either, not even your take on the set-up and conditions of the greens during the US Amateur.
I spent the whole week over there and I didn't see balls ending up in the same places on the greens because of firmnness or speed and the greens were not particularly firm, nowhere near where they would have liked them to be. If the greens had been twice as firm as they were it would not have been over the top either for Merion.
Some of the longest amateurs did hit a lot of wedges but they certainly can't do that on all the holes and if they wanted to hit wedge on some they needed to take some considerable risk off the tee.
The scoring at Merion that would be representative in any way to a US Open there was the stroke play qualifying and not the match play portion. The stroke qualifying scores, both average and medalist were right about where we expected them to be, and that was with a fairly mild qualifying set-up, much milder than Merion's administration and maintenance department wanted to see. The USGA backed it off some simply to ensure getting the qualifiers around the course in daylight which was too close anyway. That Long John Hurley from Nebraska (the longest in the tournament) was off last and unfortunately played the last 2-3 holes in way too little light.
Merion the course can definitely still hold a US Open in my opinion. I firmly believe that for anyone (including the USGA, tour pros etc) to simply look at the lengths of the holes on that course and conclude that tour pros would hit 10 or 12 wedge approaches is really missing what Merion is all about. Theoretically they could hit 10-12 wedge approaches but if any golfer, US Amateur calibre or pro could hit 10-12 wedge approaches from the fairways of Merion then they definitely deserve to potentially shoot a good score below par. I say let any Tour pro see if he can get 10-12 drives in those fairways within wedge approach range if the course is set up firm and fast!
The bigger problem is Merion the club with its lack of space and infrastructure. And then there's Merion the membership---do the members want another Open or not? If the USGA offers Opens to golf clubs accepting one may not be automatic. All I can say is the sentiment within the club is very mixed---with some very much for another Open and some very much opposed. But those that run the club say if an Open is offered to them they feel the club would accept it.
In any case, if Merion is going to be offered another Open any time soon will be known one way or another within the month.
