First trade: massive overpay on Boston's part. The Knicks get a quality wing in Green, a $12 million expiring contract, AND relief from Amare's horrible contract all for the price of a guy they've been openly shopping for two years?
Second trade: you completely decimate Golden State's frontline depth; not a chance they bite on that with how injury prone Bogut is. Also, Bogut's not gone after this year; he just signed a three-year extension with the Warriors. Thompson, Barnes, and Curry are all young and they've added Iguodala to the mix - they're in prime position to contend for years. Of the playoff teams from last year, the Warriors and the Rockets probably have the widest contention windows in the West (I'd say the Thunder are there, too, but their ownership greatly limits that).
Third trade: of the three proposed deals, this is the most plausible, but I still don't see it getting done. No particular reason why, I just don't think the Jazz would entertain it.
