Celtics’ legend Bill Russell, a civil rights icon, won two NCAA titles with San Francisco, the 1956 Olympic gold medal and 11 NBA titles in 13 seasons.

Boston dropped to 13-13 with Wednesday’s uninspired loss to the Clippers, and might need to explore the trade market for a needed boost.

Guard Dennis Schröder scored 31 points, but also had eight assists and only turned the ball over once.

Donovan Mitchell scores 34 points to beat Jayson Tatum (37 points) and Boston.

Al Horford became nothing more than a backup center in Philadelphia, but his revival in Boston has been a bonus for the Celtics.

Jayson Tatum leads the way with 26 points and 16 rebounds, and Boston limits Joel Embiid to 13 points in an 88-87 win.
