Miami are overloaded on the wings
SG: Max Strus, Tyler Herro, Victor Oladipo
SF: Jimmy Butler, Caleb Martin, Duncan Robinson
They need a trade to even out that team. They have nobody at PF and none of those guys are well suited to playing PF. Jimmy would be their best option. Caleb Martin (6-5 205lbs) or Vic Oladipo (6-4, 215lbs, long) is the 2nd biggest wing.
Herro is the obvious guy and Durant is the obvious target. If that doesn't come to fruition ... I wonder what they will try to do because right now they have 6 wings who they consider rotation caliber players without enough minutes to go around. And no PFs on the team.
