PHX just signed Rubio, why would they give up more pieces to add Russell?I have already given examples and suggested teams in the O/P...
The Magic I think would probably be willing to give away Gordon if they were to add Russell in their roster... They clearly focus on Isaac more than Gordon for their future and have resigned Ross next to their constant Fournier as to end up with a full and competitive roster... Then they could add Iwundu and a pick perhaps?
Another very possible destination for Russell could be the Pelicans... Here is how this could possibly work... Pels sign and trade Marcus Morris and add Hurt + a couple of picks...
Another possible intetest for GSW would be the Suns (but I doubt that Russell would want to end up there)... Oumbre packed with KCP on a sign and trade for both + a couple of picks could work....
Then it's any team in the league with cap space to spend... Sign Marcus Morris and KCP on a sign and trade, add a role played and a pick and it should work...
Bottom line there are ways to make this numerically work. However, I don't see any team willing to gut themselves to help GSW or take on Russell. Seems the more obvious answer if the trade were to be amended would be for GSW to be told to get bent and keep Iggy, if the goal is to move Russell for the best assets and other teams are offering players and picks.
