Home court advantage is for the Celtics, but as what we have witnessed in the past games, a small mistake could be costly to a team, so it's just a matter of what team will make the less mistake will win.
Actually, in this series, there's no such thing as homecourt advantage. Both teams already lose on their respective home courts and they aren't distracted even playing against the crowd. This is what we want to happen, a close series where we don't know who will win until we see the final result.
One mistake, it will cost them losing. One good opportunity, it will cost them winning. Generally, both teams need to minimize their mistakes and always take advantage of every possession.
Win or go Home next game, an intense match we want to witness.
