No, this is a legitimate remark, not that I have any inside information on the opinions of club members. But when I dissect Rock Creek with friends who have played the course, a recurring critique is the complexity of the greens. They are not severely tilted, but they are very complex, and reading greens there is hard work.
I doubt they will redo all of the greens, though.
By the way, I think Rock Creek is outstanding, and every time somebody asks me whether they should visit, I enthusiastically encourage them to do so.
