The Sixers sense recently posted 4 Tobias trades that give Philly a chance to better replace Harden. When Harden walks, they will have about $10M in cap space. This brings them up to 18 to throw at a guy like Harrison Barnes, Jerami Grant, Dillon Brooks, or Caris Levert making your line up Ball/Caruso Maxey/Melton (Barnes, Grant, Brooks, or Levert)/Jones Jr. Tucker/cheap FA Embiid/cheap FA (probably BBall Paul)
