Hey, get out of there, Marcin Gortat! That's not your team. Maybe he just really likes huddles.
Down by 17, Boston could have used six players on the court. Gortat casually walked into the huddle after a foul, pretended like he belonged, and no Celtic kicked him out.
Then again, Rajon Rondo also enjoys visiting opponents' huddles, so maybe the similar tactics garnered respect.
