Was there a Pete Dye course that could be called revolutionary? Teeth of the Dog? Harbour Town? TPC Sawgrass? Though I believe the latter would be concept extensions of the preceding two designs.
Something that had not been seen up t that point in architecture?
Tony, I think so, and I don't think it was either of those or any among his later courses. His early look and play style of golf courses was radically different than the RTJ era by design. And, unlike Cupp's geometric course, which was never emulated, most gca's took some elements of Pete's style, like pot bunkers, tie walls, long water hazards, a bit of a rugged vs. manicured look, etc. etc. etc.
That is why I nominated him, because his overall style had a lasting influence on architecture. If we had to go with one of his early courses to satisfy your OP question, it would probably be the Golf Club, and/or maybe Harbor Town. Meaning no disrespect to it, I always viewed TPC as almost a cartoon version of some of the ideas he developed much earlier in his career.
As always, just my sometimes fractured humble opinion.
