Thomas, 33, has averaged 41.3 points in three games with the Grand Rapids Gold of the G League in the past week. There have been three 45-point performances in the G League this season, and Thomas has two of them -- including his 46 points on Feb. 26, the most in a league game this season according to ESPN Stats & Information.
Thomas had All-Star seasons with the Boston Celtics in 2015-16 and '16-17 before a serious hip injury derailed his career. He has spent most of the past two seasons out of the NBA.
