First half beatdown: The Celtics offense seemed to figure something out in Oklahoma City and that mojo carried over to Detroit right out of the gate. While it was an off night for the C’s primary options (Al Horford, Kyrie Irving and Jayson Tatum combined for 13 points), the defense was locked in for all 48 minutes. Blake Griffin was held to seven points while the Pistons shot a dismal 37 percent from the field and 7-of-37 from 3-point range, managing just 40 first-half points. Meanwhile, the C’s offense was free-flowing and well balanced with five players scoring in double figures, led by Jaylen Brown (team-high 19 points). Behind some strong 3-point shooting, the C’s jumped out to a 23-point first half lead and never looked back, cruising to an easy win after what was effectively 24 minutes of garbage time in the second half.
