Italian translation at settesei.it It doesn’t take a statistician, or even a spreadsheet, to recognize that the 2019 Australian Open wasn’t Novak Djokovic’s most difficult path to a major title. We can debate whether the straight-set win over Rafael Nadal in the final was due to Djokovic’s utter...

As per Tennis Abstract, calculating slam difficulty based on opponents faced by the winner, 2002-2004 and 2006 were pretty weak. 2011-2016 were incredibly strong. This doesn't represent the years as a whole, just the majors, but it's hard to argue 2015-2016 are weak era based on the level of competition in majors. I do think 2017-2019 are weaker, but part of that is because a lot of top players were injured during this time. 2020 is just a mess of a year, and 2021 is too early to say.

I think 2016 (second half) and 2017-2018 were weak years for sure. 2019 though?
In Australia you had 2x defending champ edged by Tsitsipas, then one of best ever Djokovic destroying in form Nadal.
RG Thiem edged out in form Djokovic going for NCYGS but sadly burned out against Nadal.
W you had one of the greatest ever finals there, in form Fed playing some amazing tennis, defeated Nadal, hitting close to 100 winners , holding double MP but ultimately losing the 12-12 TB.
USO a little weaker due to Fed/Djokovic injuries, but still Medvedev fought well in the final.
Nextgens had many wins in masters and YEC too. No way is 2019 a weak year, definitely above likes of 04, 06, 17, 18.
