Stan in Major finals has been a progression, IMO. He played an impaired Nadal in AO '14, and still managed to lose a set just on nerves. But it got him over the hump of a Major win. I also think that Djokovic fed the "Stanimal" in the FO final, as you say in the bolded above. It was not just me sensing that Novak got conservative after taking the first. There were Nole fans on the live chat saying the same. He gave Stan the chance to hit red-line, which, all credit to him, he did. It was still a massive match, but I also felt that Djokovic waited a bit too long to bring a more aggressive game, and, that once he saw it slipping away, you could see the nerves get to his legs. When he played the USO v. Nole in '16, our old friend Billie put it well: Stan didn't play as great as he did at RG v. Nole, but he played that one smarter. That's what I mean about the progression.
As I said above, I think Stan had help transforming into his best beast, but he was increasingly confident from the 2nd set. Some of his best tennis ever. I agree with you on the 2011 v. Roger, and you're right that part of the drama was that it would have been stopped for darkness if Roger hadn't won the 4th. It was much more of an edge-of-your-seat match.
