The Celtics are making an investment in their young center.
Williams is coming off an encouraging third season in which he appeared in one more game than he had in his first two seasons combined. He cut down on his fouls and earned the starting center job at the deadline, showcasing athleticism at both ends of the floor and underrated passing chops.
He was tied for sixth in blocks per game during the regular season (1.8) despite playing fewer than 20 minutes a night.
This deal locks Williams alongside a core of Jayson Tatum, Jaylen Brown, and the recently extended Marcus Smart in Boston for the foreseeable future while making the 23-year-old one of the 15 highest-paid centers in the NBA.
