Jeff,
I have played plenty of courses where Rees Jones and Tom Fazio have remodelled and/or restored (and I use that term VERY loosely
) and I have to tell you in all honesty and trying to be completely fair and objective...
There ain't no way that their work comes within a light year of Renaissance, or Gil Hanse's team, or some others who actually care to honor great historic work...
And I think in one case its because he doesn't care to and believes his work is inherently superior and in the other case I'm truly not sure whether he cares to and just doesn't understand how to, or whether he just loves his own style so much he can't do anything else.
In the case of Merion, the 2D shapes as seen from the sky were accurately shaped, but neither their deeper depth, their steeper steepness, or their thick, hairy grass faces that dip way into what used to be flashed sand bear any relation to anything that ever existed at Merion in the previous 90+ years.
I really don't think there is anyone in town who would contest that assessment, honestly.
