Since there is so much discussion about draws in general, I was curious about digging up some numbers. I totally agree that ranking does not tell the whole story (far from it) but the interesting part is that there is no subjectivity involved.
Draws where all 5 opponents faced by the big 3 in their quarter section - R1 to QF- were ranked the highest = in the top 50 ( all slams played in their career every time they made it to QF):
1-DJOKOVIC: RG 2014 ( lowest ranked opponent faced = #44)
2- DJOKOVIC: RG 2006 (LR faced = #46, #28)
3- FEDERER: AO 2013 (LR faced = #46, #43)
4- FEDERER: AO 2010 (LR faced = #47)
5- DJOKOVIC: W 2012 (LR faced = #48)
6- NADAL: AO 2017 (LR faced = #49)
And since this thread claims "toughest draw of all time", let's look at the most unfair draws of all time between the big 3 for the quarter section.
Highest ranked opponent in all 5 rounds:
DJOKOVIC: USO 2008 (between Nadal, Fed and Djoko)
DJOKOVIC: W 2012 (between Djoko and Fed)
FEDERER: USO 2017 (between Nadal and Fed)
Yep it happened only 3 times and never to Nadal. Note that all 3 times, the recipient of highest ranked competition across the board did not win the slam in the end, did not even reach final as a matter of fact. So maybe extremely imbalanced draws do matter a bit.
When it comes to draws, Djoko gets the short end the most often and Nadal the least often in general. So who's complaining again?
