Aaron:
The Aronomink bunker project was highly unusual in that they actually built the bunkers that were drawn in the field (and very detailed field drawings) in Ross' own hand but not originally built on the course. No one really knows why app 80 of Ross' Aronomink bunkers were divided up into sets of two and three bunkers in basically the same places as Ross' single bunkers.
Some suspect it was the work of his foreman, J.B. McGovern who was an Aronomink member and green chairman. A nearby nominal Ross course (Jeffersonville) that it is believed McGovern did and Ross had little to do with also had those multi-set bunkers that apparently had some local notoriety (judging from an ad for Jeffersonville in an Aronomink tournament program).
There is no proof at all that Ross designed those multi-set bunkers or had anything to do with them. Tom MacWood might conjecture otherwise but he has no proof at all.
So the club was left with a dilemma---eg to built bunkers that Ross drew or take a chance on a bunkering scheme they could not be sure really was Ross. (Much of the original Aronomink bunkering had been removed by the likes of RTJ, so it was not on the ground during the recent bunker project)
They chose to go with Ross' own drawings.
Furthermore, Tom MacWood seems to conclude that sets of 2-3 bunkers in the places where Ross drew singles constitutues a "bold" design while the single bunkers that Ross drew constitutes something that is "dulled down".
Perhaps Tom MacWood believes that the a large quantity of bunkers on a golf course constitutes "bold" and less bunkers constitutes "dulled down". That's a pretty shaky architectural theory to go on, in any case.
I'm really not sure how or why Tom MacWood comes up with these kinds of characterizations about Aronomink because the fact is he has never been near Aronomink in his life.
The term "Rossification" is his term, no one else's. If Rossification at Aronomink means building bunkers that Ross drew for Aronomink then I say, so be it----and so did Prichard and the club.
The bunker project at Aronomink has been extremely well received but that makes no difference at all to Tom MacWood, because he thinks of himself as the lone defender of the dead guys and their work.
In the case of Aronomink he's probably defending the work of dead guy J.B. McGovern, not dead guy Donald Ross. He may try to argue otherwise and that the multi-sets had to be Ross but the fact remains he just doesn't know that and has no proof of it at all.
