BOSTON (CBS) — Isaiah Thomas provided the Boston Celtics with a huge spark off the bench as soon as he arrived from Phoenix at the trade deadline, but it wasn’t enough to take home the NBA’s Sixth Man of the Year award.

Those honors went to Toronto’s Lou Williams on Monday, with Thomas finishing second. Williams, who averaged 15.5 points in 25.2 minutes per game off the bench for the Raptors, finished with 78 first place votes, while Thomas finished with 33 first place votes. Clippers guard Jamal Crawford, who has won the award twice in his career, finished third in the voting.
