According to Bulpett, Celts not done dealing.
With the drafting of Carsen Edwards and Tremont Waters, I doubt Wanamaker would return to the Celts if he knows he will just be sitting on the bench again.
Celts have Kemba, Smart, Brown, Hayward, and maybe Carsen as guards.
So why would Wanamaker come back if the Celts already have a lot of guards?
