So Nadal and Djokovic meet twice a year and that saves it from being weak?
Since 2018, Nadal and Djokovic combined have played 375 matches. Those 8 matches against each other are supposed to salvage the other 367 against mostly weaker competition?
And if we go by your standards, from 2005-2007, Fedal met each other 13 times. They were both younger and played higher level matches against each other.
Nadal stopped Federer from racking up:
- 3 extra slams
- 3 extra M1000
- CYGS and/or Federer Slam
Federer stopped Nadal from racking up:
- 2 extra slams
- 2 extra M1000
- 2 WTFs
- 127 extra weeks at #1.
So comparing 05-07 Fedal vs 18-21 Djokodal, they competed over:
5 slams vs 4 slams
5 M1000 vs 2 M1000
2 WTF vs 0 WTF
So either call both 05-07 and 18-21 weak, or neither of them weak. If anything, both are weak but the current era is weaker as Fedal contested more big titles in 05-07 than Djokodal did in 18-21.
