Celtics get a center in Bam that is elite on defense and is young, and doesn't have a game that's near identical to tatum's. Robinson is an elite shooter and gives the team more space to operate. Kleber is a solid all around PF. Powell is a good backup center.

Heat get another two-way wing but unlike Butler he can hit the 3 very consistently, and unlike Herro he is a great perimeter defender. Timelord is a solid starting center and is good defensively. Reggie Bullock is a okay backup wing player who can shoot.

Lowry-Brown-Butler-Tucker-Williams

Mavs get Horford who is a solid defense big man and is an upgrade from those other players, can play next to luka and kp because he can shoot and defend. Aaron Nesmith is a nice young wing that can develop into one of the better 3 and D wings in the league.
