Oh I know, the wrist but he's 28 years young coming back to a much weaker tour than Delpo had to face so there's certainly opportunity.
The man is a USO champ, AO Finalist and two time French Open finalist. It's clear if he returns close to his top form he can compete at all these Slams in the coming seasons. Where would you want to see him win most?
I use 2 additional Slam metric as Wawrinka and Murray are the only ones recently outside Big 3 to win multiple Slams so there's that.
