Joe Mazzulla explains why Celtics face ‘tough test’ in first round vs. Sixers

The Boston Celtics and Philadelphia 76ers are set to meet for the 23rd time in the NBA playoffs on Sunday, reigniting one of the league’s most historic rivalries. To coach Joe Mazzulla, this Sixers team in particular presents a challenge for the C’s.

“Philly’s a great team, as you saw throughout the season, and to get to this point with all the injuries that they’ve had and to be where they are now, it’s gonna be a tough test for us,” Mazzulla told reporters at Friday’s practice, per CLNS Media. “We gotta be ready for it.”

To secure a playoff spot, the Sixers overcame the challenge of turning a shorthanded roster into a contender. Both Joel Embiid and Paul George played less than half of the regular season, forcing coach Nick Nurse to adapt. Guard Tyrese Maxey inherited the No. 1 role, averaging a career-high 28.3 points across 70 starts, while rookie V.J. Edgecombe averaged 16 points on 43.8 percent shooting in 75 starts.

Obviously, playing without two of your top three players isn’t ideal. However, as Mazzulla explained, the Sixers managed to find a silver lining in what many would consider a throwaway season.

“With those guys out throughout the season, their role players have been able to develop into big-time roles,” Mazzulla said. “With the way (Kelly) Oubre’s playing, (Andre) Drummond has been playing, (Adem) Bona has gotten better and better, (Quentin) Grimes off the bench — so I think they’re a very, very well-balanced team. I think they’re playing some of their best basketball as they get healthier and healthier, and obviously they’re a well-coached team.”
