None...but before you grab your torches and pitchforks, let me try to explain.
Sure, on the surface, a trade for Davis, Towns or most anybody else that has been listed in this thread so far, sounds great...but none of them would be a 1 for 1 trade.
So in order to make it happen, we'd have to give up other core members of the team. At the deadline, all the talk about Butler had us shipping out several players AND the Brooklyn pick which became Fultz. Some of these players have provided us some really great moments in the playoffs so far.
This way, we get Fultz for FREE...and I'd rather find a place for him to grow and become the basketball player he is meant to be with as many of our core players as possible. Adding him alone will be one of our best offseasons in the past decade...and if Hayward also joins the Celtics, next year will be just as exciting as this year has been.
