I think Russ will likely not give back a lot or any. Blake had a wide market. Russ has little to no market unless he chills the hell out and shows he can be a bench guy. He may be able to repair his value but it will require eating so much pride... to date he has shown zero ability to do that. He may have to sit out for a year to get his head in the right space for the next phase of his career like Melo did.
That is why I said theoretically he could give up salary. Not saying he will but I wouldn’t be surprised if he did give up some.
