Jayson Tatum scored 32 points and Jaylen Brown added 19 as the Boston Celtics beat the Chicago Bulls 107-99 on Monday and reached the midway point of their season with the NBA’s best record.

Boston has now strung together three straight wins and their first win streak of the calendar year after losses to the Denver Nuggets and Oklahoma City Thunder.

The Celtics’ power forward Grant Williams was interviewed following Boston’s win over Chicago on Monday night. On big man Robert Williams and his impact in his first start, Williams said, “Rob’s presence is contagious.”
