You can look at this two ways. An architect who has done 100+ courses is likely to have done a few that look really different, just by sheer happenstance, but the main body of his work might be very similar. Then again, at that level, it's much harder to keep the work fresh than an architect who has only built 10 courses or even 25 as I have.
For Tillinghast, SFGC and Somerset Hills (two of his earliest) are very different than all those parkland courses he built in the northeast in the 1920's, but the latter are not all that different from one another.
I thank John Kirk for his nomination but I don't see how I could be considered when John Kavanaugh just a week ago told me I'd built the same green 500 times now.
I will keep trying I guess. I haven't played it yet but I hear the new course at Aetna Springs is really different.
