With Bradley being moved for Morris, this same idea could work. As far as Yabusele, the guy on twitter thinks it's possible he was promised he would be brought over and they don't want to go back on that.
IT. Rozier. Jackson
Hayward. Smart
Crowder Brown
Morris Tatum. Yabusele
Horford. Theis Zizic. Mickey
That leaves one roster spot to used the room exception or a minimum salary. I would still like to see Gerald Green brought back at a minimum salary. If they decide to use the room exception on a frontcourt player, they could always waive Mickey. However, if they bring in another forward, and keep Crowder, it's going to be tough to find minutes for Tatum. They may decide to roll with what they have so Tatum and Brown can get enough playing time.
