They shouldn't. Faried has more value than anyone we have except Rondo. He was playing for a spot with Team USA this month. Any Celtics there? Gallanari and Green are roughly the same player, maybe Green is more athletic and Gallanari is a better shooter. Equally bad contracts. Bass/Bogans for McGee would just be a salary dump I think.
If the Nuggets would make this trade we should do it in a second. Gal is younger, taller and a better shooter. Faried is an upgrade on KO and McGee is a legit center with no brain. Would be a coup for the C's
You'd more likely see this trade which is just a stripped down version of yours:
http://espn.go.com/nba/tradeMachine?tradeId=o6at8efBecause it moves so much salary away from the Nuggets in 2015 and isn't a slam dunk for the C's due to McGee's lack of a brain. That kind of salary dump is probably more along the lines of the trade we'll see this season, though closer to the deadline I'd imagine. For the record I'd reject that trade I posted above. Rather have cap space in 2015 than McGee's shenanigans.
