G.O.A.T.
You shouldn't hide behind the hypothetical nature of it. Let's be honest here. Sinner could not even straight set an awful, ancient Djokovic and needed a Medvedev collapse to lift the trophy. He's not touching prime Federer.
“Prime Fed” is not just any old hypothetical, though. How could any of us have reliable information on what was going on in 10,000 BC?
