I never liked the "hack it out" rough of the U.S. Open. That takes away too much of the shot making. I like to see players need to deal with flyer lies, and go for it when they shouldn't thinking they might get lucky and pull it off.
The aspect of the U.S. Open that I really like and that I think is missing here would be quality greens. I think Oakmont provides the standard -- very fast and smooth. "Fast" isn't possible this year due to the undulation, but I do think they missed the "smooth" part. The West Coast grasses are problematic, and Fescue is perhaps the worst. I'm not sure I understand why Bent would not work at Chambers Bay. But, it is a public course, and they probably wanted to preserve the "native grasses" aspect, though "natural" certainly doesn't fit the terrain. That said, I do love how they carved out most of the holes. I would play it for sure, and enjoy it.
Appreciate your point but to me, the US Open wouldn't be any different from the Colonial, Memorial or Players Championship game. What made the US Open different for me was the penalty for not keeping it on the fairway while having to navigate some very long holes (forcing players to take chances). I used to go to Firestone a lot and the problem is that players started playing "off course". In other words, they'd play down the neighboring fairway, skip balls off the water and off the crowd, and dump balls into the sand to mitigate the risk of rolling off the back of the fairway (up and down from the sand has to be ~ 80% from greenside bunkers).
Regardless, watching the US Open yesterday, I just couldn't get into it. It just seemed like another tourney.
