This is a stretch at best. Nick why would GS do this? Wouldn't they need something else in return? What else would NY give, if they're not already giving too much? I don't think this is realistic.
Actually, take Anthony Morrow out of the deal and it's about as realistic an NBA trade as you are going to see. However, it doesn't work without another small $800K-$1MM salary leaving Golden State.
Now I guess Mikki Moore could be that player but then that limits the trade until after Dec 15th and then what incentive does Boston have to give up a first rounder.
New York is getting the expiring contracts they need to open space for two max level free agents. Golden State is getting a young big with potential and getting out from under Jackson's contract while at the same time getting a first rounder and 2 second rounders. Boston is getting the wing they need and at the same time swallowing a pill they really don't want but will take under the circumstances, that being Jackson's contract. But to take the contract that means they probably won't resign Ray Allen next year and so Anthony Morrow, Ray's replacement is in the deal.
Now maybe instead of 2 second rounders New York throws in this year's 2nd rounder and a 2011 or 2012 first rounder. Maybe those picks make up for the loss of Morrow. Besides, with Ellis, Curry, Watson, Azubuike, and Maggettte Golden State has tons of wings and guards to spare and the picks should easily find a Morrow replacement.
So turn a NY 2nd rounder into a first rounder if you think the deal is unreasonable. I think that sweetens the pot enough and gets this done.
