The changes described do not particularly trouble me. Green expansions that restore putting surfaces and hole locations lost to many years of mowing make sense to me. Ruddy has a great brand and seems to be very respectful of Colt. He does not appear to be trying to put his 'personal stamp' on the restoration, just adjusting for the modern game. I would hope he would 'restore' the new third green in a manner consistent with the original, just 40 yards further back.
I've seen both sides of this equation, at Orchard Lake Foster's green expansions were consistent with the original Allison greens and have given us numerous terrific new hole locations. At Desert Forest, Zinkand was less respectful of Red Lawrence's original surfaces and green surrounds and the result is a divided membership and greens that are simply too difficult for daily member play.
