Yes, I did mean to offer my own opinions, but wanted to let others have a go, first.
I think everyone will agree that a year with no Wimbledon is bizarre and only felt like a significantly hobbled year, even though 3 Majors did get played. The right decision, especially since they couldn't really put it off to autumn, and they had the insurance, but still. And as
@El Dude, said, a strange year with so little of Roger. I hate to say this, but it started to feel like a preview of when he retires.
As to the worst, beyond the pandemic (in general) and its effect on the tennis calendar, (in particular,) I think there has been some appalling behavior on the ATP side. I don't think I need to reiterate some of Djokovic's transgressions and missteps, but Zverev can be called out again, for claiming to quarantine after the Adria Tour, then obviously not doing it. One of the best things, I have to say, and most deliciously ironic, was Nick Kyrgios calling out others on their misbehavior on Twitter.
Worst of all, perhaps, is the ATP making no statement of policy or investigation when Zverev was accused of abusing his former girlfriend. For a sport that clutches its pearls at swearing on court, racquet abuse and has an actual policy on player behavior, they might have reacted in some way. I'm not taking a position on his particular case, but only calling out the ATP for their silence on the matter.
On the personal side, of course Nadal winning RG and beating Djokovic so comprehensively in the final was a highlight. And if it couldn't be Rafa to win YEC, I was glad to see Medvedev coming good.
