The Boston Celtics must take pride in their Game 2 display against the Philadelphia 76ers, and embrace the challenge of a hostile road game, says Jaylen Brown.

Joel Embiid's return from injury could not inspire the 76ers on Wednesday as Boston cruised to a 121-87 victory to tie the series.

Brown top scored with 25 points, as Embiid and James Harden, who scored 45 points in the 76ers' Game 1 win, were kept under wraps.

Next up is a trip to Philadelphia for Game 3, but Brown believes the Celtics have nothing to fear.

"I think we've just got to take more pride in ourselves. That's it," Brown told the media.

"I just feel like we underperformed last game. We wanted to come out and play to the best of our ability, and that's what we did.

"Hostile environment. But it should be fun. We should all be excited to embrace that challenge."

Coach Joe Mazzulla was blunt in his assessment of his team's reaction to their defeat in Game 1.

"They were angry, frustrated," he said. "Angry and p*****. Yes [I liked that]."

While Jayson Tatum struggled to make too much of an impact, Malcolm Brogdon added 23 points from the bench for Boston, tying a playoff record for the Celtics in the process as he sunk six three-pointers.

"Our strength is our depth," Brogdon told reporters.

"The way the roster is constructed, we got guys like me, Derrick [White], Grant [Williams] that are playing behind our two superstars and ready to [contribute] when we can."

Celtics guard Marcus Smart, meanwhile, credited Brown's on-court leadership.

"We've got to tip our hats to him, he started that whole momentum for us," Smart said. "We just had to follow his lead.

"When you've got one of your best players setting the tone like that, it's hard for you not to follow. Our defense has been slipping and we wanted to come out and get back to what we do best."
