Djokovic won a slam at 20 years old straight setting Federer only losing one set the whole tournament, he already backed up his breakthrough. At Med's age at his first slam final, Djokovic won his second slam only losing one set and it was his fourth final.
Djokovic's variety and touch was pretty impressive back then especially the drop shot. I guess once the courts slowed down so much, he had to mostly just perfect his baseline game and endurance to compete against Nadal. I really do miss the more aggressive young Novak, but he had to change his...
Djoker had a very complete game at a young age, easy to predict that he'd win slams. Many of the current younger players have a lot of holes in their games, even Med has a big hole to his game despite being ranked no.2.
Comparing a lot of these players to Djokovic is insulting tbh, especially Zverev, Coric, and some others that he listed. While his net game and court positioning aren't good for doubles it's good enough for singles.
