No doubt Novak was not in his peak form during all of 2020, but the situation was the same for all players. Players chose their schedules, not Novak or anyone else. Fact is though that before the Covid break Noval won the AO, beating Federer, then Thiem in the finals. He also won the ATP Cup, beating Nadal in the finals. Even though it took Novak 5 sets to beat Thiem in the AO final, still he won. He then won Dubai. After the break, in his supposed lousy form he won 2 Masters, and reached the FO final. Had he not been defaulted, he may have won the USO. No doubt Nadal and Novak are no longer in their peak form, but like Federer at their age, both could still win more important tournaments or perhaps a slam or two.
