“He knows this team,” Doc Rivers  said. “He was in their training camp. He was in their practice. He knows their personnel. I just thought he may be able to help us in some way.”
As for Shaq, Rivers said that he remains a possibility for Game 2, if not Game 3 back in Boston.
“He’s getting close,” Rivers said. “We actually had to make a decision so that’s better than what we had to do in the past. Maybe next game, if not I would say for sure Game 3.”
