The Bulls get PF depth with Obi, and take a flyer on Reddish as a 3 and D guy that Thibodeau didn't seem to have any interest in giving minutes.
The Knicks get a young guard who fits RJ's (and maybe Zion's?) timeline better than DRose and Kemba, another pick to use in trades in targeting big names in the offseason, and a little extra wiggle room in the cap.
