The first-round series between the Celtics and Bulls started off quite intriguing with the Bulls taking the first two games in Boston, but the matchup fizzled to an end in Game 6, as the Celtics cruised to a 105-83 victory Friday night to take the series 4-2. 

With the Celtics leading by 30 points at times in Game 6, there wasn't much to take note of, except for an interesting moment late in the game.

During the closing minute, the Bulls fans began chanting "fire Hoiberg," making it clear they were not happy with their second-year coach. It's not really clear what they expected him to do with this roster, but nevertheless, they were not pleased with this result. 

But the fans were not the only ones upset, as Brad Stevens seemed to be perturbed by the calls to axe his fellow coach. As the chants broke out, the camera happened to be zoomed in on Stevens on the bench, and it looks like he's saying "shut up."

Other NBA coaches rave about Stevens -- Gregg Popovich even went so far as to say, "I really respect the hell out of him" -- and moments like this, along with his actual coaching ability, are a big reason why.
