His value is diminished. I hope he has learned that he does not do himself any favors with the diva act. I would not mind him coming back at a reasonable amount if he is no longer the diva.
As for the trade, I would not characterize it as "robbery." Whether Gaines re-signs with the Bills also will play into how to evaluate that trade.
Also, nothing will ever make up for how much we overpaid to draft him.
