I'm starting to get the sense that the end might not be far off for Daniil. I'm not predicting he'll retire at any point soon, but wouldn't be surprised if he's out of tennis by, say, two years from now. Meaning, I wouldn't be surprised if some variation of the following occurs:
Focused on family and just not feeling it, Daniil has his worst season since 2018, drops out of top 10. Re-evaluates, gives it another go in 2026, but just can't find his form--or at least drive--of 2018-23. Retires in 2027 or 2028.
Of course there's the chance that family life drives him nuts and he re-focuses on tennis, re-finding his form and playing for another 5 years. But I'm leaning towards the above (in some form or fashion) as more likely.
