In the NBA regular season, the 76ers beat the Celtics 102-100.

In this campaign, Grimes felt very good coming off the bench. He played 28 minutes, making 6 of 10 shots, 3 of 6 three-pointers, 3 of 3 free throws, and scored 18 points, 6 rebounds, 4 assists, and 1 block.

During the offseason, Grimes had trouble negotiating with the 76ers, and finally accepted a qualifying offer of US$8.7 million.
