Other than Maxwell redo's of the 7th and 10th holes, I'm not sure what other greens he changed. He made relatively minor changes to several, but I've never been clear which ones, though I have some guesses. Chris Clouser is the best source for that info. perhaps he will chime in.
The 5th and 14th greens are MacK's. Maxwell did very good greens. But he sat at the feet of MacK.
