I really don't expect the score of the series is going to make any difference on when they bring him back. Even if we are up say 3-1 and he is ready to go, you want to get him out on the court. There is going to be a period of time where he is getting back into game shape. You are not going to put that off if he is ready, no matter what the series is at. The more games under his belt for the second round, the better. It doesn't matter if we are up, down, or tied.
Now when that is going to be, I have no idea. It is impossible for any fan to know.
