Thompson spent nine seasons with the Cleveland Cavaliers after being drafted by the team fourth overall in 2011. The Canadian forward was an integral part of the 2015-2016 Cavaliers team that, led by LeBron James, won an NBA championship, breaking the city of Cleveland’s 52-year championship drought.

The 29-year-old is coming off a year in which he averaged a career-high 12.2 points per game. Thompson has also averaged a double-double in each of his last two seasons.
