Yeah I'm not 100% sold on this being a complete one-sided trade either. Gordon is on a pretty expensive deal and has played 42% of the possible games in the last 3 seasons. That is dismal and he's expensive. If NO still believes in him they do hang up the phone. If they'd like out then it's certainly a discussion worth having. I personally think Bass is worthless on his current deal. He's an expensive bench player. Something like Green+Lee for Gordon
The problem isn't the equality of the trade it's that we don't have much NO wants. They could use a Jeff Green but probably don't want to pay him $9M/yr. That is most likely the piece that moves this trade. Green's contract and late-season production make him an ideal candidate for this kind of trade.
Additionally NO has Gordon locked up for a few years and no real cap problems so I don't see why they wouldn't try to get some mileage out of him before they jump ship.
