I don’t want to make too much of this (though I’ve brought it up several times in the last week!), and I’m not sure if this exactly answers your question about Oakmont always having rough, but this article is from 1919, when the US Amateur was held there:
“The number of traps on the holes and the narrowness of the fairways made straightness imperative, a feature which was lacking at Detroit, that other extended and lengthy course where the championship in 1915 was played. The average number of bunkers and traps at each hole was in the neighborhood of eight, with some having as many as fifteen, and a few as low as five, these on the short holes. But there was rough everywhere, except in the fairway and it was the intertwining sort which makes it difficult to play a shot any distance. In a word…it can be said without a shadow of a doubt that there never was a championship in this country held on a course which could be regarded as an equal to Oakmont, which is praise indeed.”
[As both Joe H and TE Paul raised on another thread, though, I'm not sure the rough in those days could have been the kind of rough we/Oakmont have today, given today's technology/irrigation etc....but it certainly seems to have been considered quite penal in 1919]
Also, I don’t want to copy all of RJ’s post, but I thought he raised some good questions, and they were what I was wondering about as well. In short (RJ, I hope I haven’t cut the heart out of your question):
“Tiger may consider what he would NOT do based on real world playing experience at Oakmont, but no one knows what Oakmont Lite could provide for the masses because it hasn't been done….So my point is, how do you know what you would do at Oakmont if you haven't actually seen it in a maintenance meld and in a competitive situation….Frankly, I'd like to see a women's tournament or senior am there with the Oakmont Lite maintenance meld, and then have a more accurate gauge of what architectural features might be translated more to widespread public appeal.”
