There's only one spot remaining in the NBA's Conference Finals, and Friday night, that spot could be filled if the Celtics beat the Wizards in Game 6.

Boston crushed Washington in Game 5 to take a 3-2 series lead, but they got destroyed in both games in Washington earlier in the series, so closing out the Wizards on the road won't be easy.

That said, the Celtics dressed for the occasion of closing out the Wizards.

Trolling from the Celtics?  There's a good chance that's the case no matter how much the players deny it.

Fans, on the other hand, loved the power move from the players.

There's a much deeper reason for the Celtics wearing all black to the game that fans might not know about.

As the Celtics website pointed out, on January 24th, the Wizards wore all black to a game against Boston and won easily.

If Boston doesn't win, we imagine they'll be asked about the choice to wear all black after the game.
