Nice take & never really looked at who accompanies these players esp. at bigger tournaments. I’m convinced players like Novak r just testing the tennis decision makers to see how far they will bend esp. to the top players’ requests but w/ all the tennis missed this season & other sports resuming, I still see all top players attending USO IF it is to b held.I'm not convinced that holding the US Open is a good idea, but I will say that if it is held, bringing just one team member along would level the playing field a bit. That could make things pretty interesting! The rich top-ranked players finally will be without the advantage of their egregiously huge teams. I would like to see which high-ranked players are able to overcome that challenge, which ones crumble without their throng of helpers, and which lower-ranked players would shine, since many of them probably only bring one person with them under normal conditions anyway.
Edited to add/speculate further: I think Djokovic and Nadal would probably struggle without their respective teams more than Federer would, unless Federer still needs lots of extra post-surgery physiotherapy. Zverev wouldn't do well without his team as he seems to be sort of psychologically fragile and needs his team to stabilize him. Tsitsipas has the potential to do well without his team there because he is a creative and thoughtful player and is usually in his own world on the court anyway, plus he is young & in great physical condition, but I hope he would bring someone other than his father to avoid family tension - maybe the smug Patrick M would help him? Thiem is another top player I have confidence would do well on his own. FAA I'm afraid would be toast. As for lower-ranked players rising up, that's harder to speculate. Maybe Struff and Kukushkin. I doubt Kyrgios would even show up without fans.
