You are probably correct Terry. They would mess with it, and the club has been messing with those things at Riviera for years. But they wouldn't have to mess with it to produce a compelling challenge, even with these guys bombing it a mile. Of course the same could probably have been said about Merion, and look what they did there.
I too am curious about what they will do at Pinehurst. One would hope that they will at least leave some width, but we'll see I guess.

Jim, Probably the score would scare them, and as Terry said they'd most assuredly trick it up whether they needed to or not. But doing so would be a pretty easy matter, I'd think. For example, I didn't go over and watch this year in person, but on t.v. it looked to me like the kikuyu rough was cut way down, and that the golfers were having relatively easy time from the rough compared to how it often plays. Kikuyu is a weird grass and it almost reminds me tiny bush. If it is cut low, the ball sits up on top of it. But if kikuyu is higher, the ball drops down below the thick leaves and stalks and it becomes almost impossible. Allowing the kikuyu rough to grow a bit would make the course much harder than we saw this last weekend.
I wouldn't hold my breath for an Open there for a number of reasons and I think this is good thing. I'd hate to see them further screw up the course to appease the USGA. Plus, the players and announcers would be crying about the greens from the moment the tournament was announced until long after.
