Weinman will also shift his focus toward pro scouting and draft personnel.

Prior to Chicago, he spent seven seasons with the Cleveland Cavaliers, first as Vice President of Basketball Operations (1998-99), and then as President and General Manager of the club (1999-2005).

He was a two-time NBA All-Star and earned All-NBA Second Team honors in 1984.
