Johnson was in the starting lineup Saturday and posted a double-double with 15 points (7-12 FG, 1-2 FT) and 10 rebounds against the Celtics. Johnson hadn't started a game since Dec. 30 against the Trail Blazers, when he scored 14 points and pulled down 11 rebounds. He was averaging 10.4 points and 5.6 rebounds in five starts coming into Saturday's contest. It's unclear whether he'll continue to start, but Johnson made a strong case on Saturday.
