Chris:
At 83, I think it's fair to say that Mr. Dye has earned a bit of latitude in the golf business.
Also, some of the courses that are marketed under his name are courses that he didn't have so much to do with, although that is NOT true of the new French Lick course, where I know he spent a fair amount of time. (For that matter, I am not sure how much of the work you liked at The Fort or Mystic Hills is Pete Dye's, and how much is Tim Liddy's, or some other assistant.)
In the 1960's through 1980's Pete's business model was to take one or two projects at a time and live on-site. In that period, he built everything from The Golf Club, Crooked Stick and Casa de Campo to Oak Tree, the TPC at Sawgrass, Long Cove, and Blackwolf Run. I think those are the courses upon which his legacy is rightly judged.
