Having seen the drawings for Rolling Green, I realize Flynn had this feature in his plans. I'll check, but I don't believe he incorporated such a feature on some of the other holes that Tom mentioned which have even more severe approaches. I realize some of the reasons for it on number #1, e.g. keeps balling from rolling back in the fairway, makes the green appear like an "island", makes the green appear more elevated then it is,... but I still don't care for the design concept.
The same goes for the two approaches at Fenway. I did not see the plans (if there even are any) from Tillinghast, but doubt he would have called for rough there. And even if he did, I think the hole would look and play better without it.
Again, maybe a first cut height would be a compromise.
And as mentioned, these guys did often deviate from their drawings (those that did drawings) both in the field and from one set of drawings to the next. It's hard to tell for sure what they actually ended up doing without having an aerial or pictures that was taken a few years after the course opened for play. Some guys like Flynn, wouldn't even add any bunkers until after a period of time passed to see how the course was played.
But regardless of what these guys liked and/or recommended, I don't really care for rough in front of greens where a run up/low running recovery shot is possible (even if it is a very difficult shot to pull off).
I assume most of you agree.
