The Fort Worth Star-Telegram (Jeff Caplan) reports: Longtime Mavs assistant coach Del Harris, who most recently served as a team consultant, is leaving the organization to join the staff of first-time head coach Vinny Del Negro with the Chicago Bulls.

InsideHoops.com editor says: Fantastic hire by the Bulls, adding an extremely well-known veteran coach to help guide Del Negro. Of course, one wonders if it should be the other way around, Harris getting the head coaching job while Del Negro learns the ropes under him and gets good experience before leading a team himself. That’s what I would probably have done. But then again, I don’t know Del Negro’s basketball mind. Maybe he’s brilliant.
