Congrats to Federer on yet another glorious hypothetical victory, by the way 
Overall mostly agree with the commentary. 2021 was a weird year, Olympics interspersed with Masters and IW/Miami either being postponed or played with no high level participation. ‘15 Federer actually played more and showed less burnout than Djokovic, which seems bizarre.
I do think Novak ‘15 was way way better than his ‘21 version so for Fed to be a worthy adversary to ‘15 Djokovic is a good achievement. However ‘21 Djokovic came with the goods in the AO/FO/Wimby later stages, especially the first two, and definitely deserves his 3 titles. Unfortunate that Federer did not get this sort of late career opportunity, but given that he lost to AO Seppi, he wasn’t doing CYGS either.
