ANALYSIS: For the first time in his nine-year career Tristan Thompson will depart Cleveland as a free agent. After trading away Enes Kanter and losing Gordon Hayward in free agency, signing Thompson will give the C's a veteran presence down low. Thompson continues to be effective as a big man in the league and is coming off his second-straight season averaging a double-double.

The deal is two-years worth $19M, reports The Athletic.
