I think Novak is still in the position to win more major titles, barring a serious injury that makes him take a step back like Rafa, Roger, and Serena. (Serena also took time off to have a kid and went through a challenging pregnancy during probably her last prime playing years and still made some finals upon her return.) Novak’s still relatively healthy, even with the stress of going deep into tournaments on his aging body, and I’m not sure there are players other than Carlos and maybe Medvedev who are knocking on the door to stringing seven best-of-five matches together imminently. We shall see CA inspires his peers to step up or even motivates older folks like Zverev and Tsitsipas, who both seem to have regressed a lot. I hope Eubanks can build on what he’s accomplished recently.
Also, we will see if Carlos’s next few years are similar to Roger’s 2003-07, after Sampras retired and Agassi was winding down, when there was a dearth of all-time greats in the sport aside from Rafa on clay (CA’s play is very physical, so I wonder how much his body will hold up), but I think Novak might remain in the mix for at least another year, putting him in contention for 4-5+ more titles. No one knows what the future holds, of course…but that’s my thinking.
