Adrian Griffin has been lauded in recent years for his coaching, as one of Tom Thibodeau's lead assistents. That praise however, has snatched him away to Orlando where he'll become the lead assistant to Scott Skiles.
Griffin worked under Skiles in Milwaukee, and has been rumored to Orlando since Skiles took over the head coaching gig there last month. This further changes up the bench, as Jim Boylen was hired from the Spurs a few days ago, and with Andy Greer getting fired along with Thibodeau.
I could imagine Fred Hoiberg isn't entirely done building yet, and with Summer League less than a month away, it wouldn't surprise me to see further unveilings in the coming week or two.
Ed Pinckney and Mike Wilhelm are currently the two hold-overs from the Thibodeau era, making it an all-new look for the Bulls coaching staff next season.
