No, I disagree and would be flabbergasted if Tom Doak attempted to state that the 15th at Merion East has an Eden concept green forgetting that the overall approach shot has nothing at all in common. Frankly, George Bahto and other Macdonald/Raynorphiles like to compartmentalize holes into trite templates or combination of template pieces fit together in some awkward manifestation. Whether to look for Macdonald's influence or that's how they see golf architecture, I cannot say. I just think it gets to border on the ridiculous.
1) The second shot at Merion East is an uphill approach, generally much shorter than the approach to the flat 11th hole at TOC.
2) There is no bunker, nasty or otherwise, front right center at Merion that corresponds to the Strath bunker. The right greenside bunker might appear to be a bunker that pinches in the right side of the green (only from the right side of the fairway and to a back right pin) but it really is a diagonal bunker along the right side of the green. Given that the preferred approach angle is from the left side of the fairway, the bunker only comes into play with a back right pin, a very dangerous shot to take in competition--better to hit the center of the green.
3) OK, there's a nasty bunker on the left flank. Thousands of greens have back to front slopes with left bunkers (as do most at Winged Foot West). Are they all Eden greens? It is funny how people like to classify things in ways that take away all meaning to the original definitions.
4) Many classic era courses have back to front tilts, especially on long approach shots. This characteristic is not confined by any means to Eden greens. The overall side slope of the 15th green at Merion is not left to right, only along the left side of the green.
