I like these unreasonable pie-in-the sky forecasts. I am going to jump in and have some fun. As a matter of fact, I drank the same type of potion that the OP drank, except that mine is even stronger It is super-fun, except for the triple vision that I am currently experiencing.
I will start with Chung. Chung will win 25 career slams title. He is already way better than Federer ever was.
Djokovic is at least twice as good as peak Fed ever was. Djokovic has far more variety and he can serve and volley better than a peak Sampras and a peak McEnroe put together. And Djoker will be hitting 160 mph aces with his new elbow. And since Fed won 4 slams from his age 31 season until now, that means Djokovic will win at least 12 more slams during those same ages. But it gets better! Djokovic won’t have to face a peak Djokovic! That is worth another 4 slams. That gets Djokovic to 28 slams right there. But Djokovic will also decline far better than Fed has too. As a matter of fact, I see Djokovic taking back-to-back calendar slams starting with his age 38 season. Djokovic will also be the greatest old player ever too. If Rosewall and Federer can combine for 6 slams after the age of 35, then Djokovic can crush that. Remember, most players get better with age. Also, tennis is far less physical of a sport than golf is. People forget that 59 year old Tom Watson ended up as a runner up in a major. Djokovic should be able to beat that.
If Djokovic doesn’t end up with at least 40 slam titles, then I will buy some beer and get drunk.
Djokovic’s final slam tally:
12 AO titles
12 Wimby titles
11 FO titles
10 USO titles
Total 45 titles
Can we say, la decima career grand slam? I say yes!
Wait. I have triple vision. That means that I need to take 1/3 of 45, which is 15. I predict that Djoker’s final tally will be 15 slam titles.
