He NEEDS to show solidarity with the team whether he actually plays a significant amount of time or not. The longer he stays out of uniform the harder it's going to be. All he has to do is suit up and be honest with Adelman why he's doing it.
He needs to do it now.
The team is healing, rebonding, assimilating new members into the fold, etc. Bobby and Erik CAN'T suit up. Pedja can and he needs to, just to show he's part of the team.
When you lose a family member, which is what this most closely resembles, the remaining family members close ranks and they often times find their ties and bonds strengthened. Pedja has to be a part of that or the isolation he was reported to have felt before will be even worse.
