Boston Celtics head coach Joe Mazzulla loves to push his players, and his halftime challenge sparked the team's comeback win over the 76ers on Sunday.

Jayson Tatum led the way as the Celtics stormed back from 26 down to defeat the Philadelphia 76ers 118-110 on the road

Tatum was shocked. Horford was in disbelief. Mazzulla pretended he didn't care. The Celtics had strong reactions to the Luka Doncic trade.

Celtics center Kristaps Porzingis was a teammate of Doncic in Dallas. "I think this is the craziest trade in NBA history. Unbelievable,” Porzingis said.

Kristaps Porziņģis, who played alongside Dončić in Dallas for 2 1/2 seasons, sounded as surprised as anyone. Porziņģis said his phone wasn’t working, so he learned about the trade when someone told him about it on the streets of Philadelphia, where the Celtics were in town to meet the Philadelphia 76ers.

Jayson Tatum scored 13 of his 35 points in the fourth quarter and the Boston Celtics rallied from a 26-point deficit to beat the Philadelphia 76ers 118-110.

The Boston Celtics play against the Philadelphia 76ers at Wells Fargo Center. The Boston Celtics are spending $5,853,648 per win while the Philadelphia 76ers are spending $9,778,0
