On ranking alone, Lleyton needs wild cards, or he back to playing in the challenger series which makes no sense. As a former #1 he can get wild cards, but eventually they get less frequent too. A depp run at the Australian open will fix the problem, but if it does not happen Davis Cup is likely to be the main goal Lleyton can focus on.
I do not see him electing to not play in Davis Cup. Even if he retires from all else (hope not!).

Q. Your ranking is obviously going to take a knock after this. Are you up for qualifying, the hard sort of grind of trying to get back into the main draws?
LLEYTON HEWITT: Probably not, no. But my ranking, for me, it's not an issue. I'll get wild cards into a certain amount of tournaments that I'll want to play anyway.
As I've always said, your ranking takes care of itself. Once you're actually in the tournament, if I can play at that level consistently, then my ranking's the furthest thing from my mind.
Davis Cup last 5 years, only harms his health, so I want that to fully concentrate on his health and playing in tournaments, and let them play until September young Tomic and Ebden.
