OK, look, I know that most of you will disagree with me on this, but really, Djokovic shouldn't even have been in the finals. His AO finalist plate deserves an asterisk all over it.
Sinner TANKED the SF match against Djokovic. He never intended on winning that match.
And yet, even with Sinner going very easy on him, it took Djokovic (who was playing noticeably better in the SF than in the F) an extremely close five setter to barely "defeat" Sinner. Even then, Djokovic still won 12 points less than Sinner. Safe to say, even when Sinner was holding back and Djokovic was playing anomalously well, the two were basically on par with each other, and if anything, it was Sinner who was overall the better player.
Now, what happened when this very version of Djokovic showed up in the first set of last night's finals match? He dominated Carlitos 6-2 in less than 40 minutes. It was only when his body finally started remembering it was 39 years old that Djokovic's level dropped substantially in sets 2, 3 & 4. But then, even in set 4, Carlitos just barely managed to scrape by.
Let's not kid ourselves: we all know that Sinner, if he were truly going all out, would've steamrolled Djokovic in straight sets, just like he did in their last four meetings. And he would've needed 4 sets at most to dismantle a rather subpar Carlitos in the finals.
