Simple solution to getting more top players to play - don't schedule straight after a GS and reduce matches to best of 3.
No, No, No
I'll take the Davis Cup B05 without the top players over BO3 with them.
With the DC I must admit I'm more seeing the problems than coming up with solutions if the overall schedule remains as busy.
Not immediately after Slam - Yes. Best of 3 - No. But final set TBs - Yes ! ( not sure that particular one changes much, just I much prefer final set TBs full stop ).
Think maybe every 2 years, the odd years, as some have suggested, might help.
Certainly very far from Kyle's court of choice. Questions have been asked about him on a fast court before with his shot prep and movement though his movement has been generally improving.
Got to dig in and find ways though when the wind, the courtspeed or whatever it may be, is not to your liking.
