My biggest hope is that Porzingis will be able to play again this season, at all. I'm not convinced he will be but we shall see. That aside I hope the team plays him when he is cleared to play. I'd prefer not to see them bring him back too soon, but I also think it would be folly to give him additional rest, in some sort of attempt to preserve him. It would be far from ideal to attempt to reintegrate him into the lineup in the Finals.
It's been nearly a month since he last played, and the team has had to somewhat move on without him. It could very easily upset the flow of the team trying to reintegrate such a major piece, and to do so in a setting where you can ill afford to give away even a single game could be problematic. But it is out of our hands, we just have to hope he can play at all, and trust that the team makes the right decision as to when and how to bring him back.
