To Chicago: Green, Crowder, 2015 LAC 1st
To Boston: Dunleavy, Snell, Bairstow, Mohammed, 2015 SAC 1st (top 10 protected)
Why for Chicago: Green is an upgrade over Dunleavy. Crowder provides "Lebron stopper" potential for a playoff matchup with the Cavs. They get a first back.
Why for Boston: Acquiring another late 1st for Green is not useful given how many we have - this takes a late 1st and turns it into what would be the 11th pick today. Having the 7th/8th and 11th/12th picks would increase our chances of drafting a star in that range, and offer enticing trade-up possibilities. The pick is already top 10 protected, so it may get bumped into the future, but this makes CHI more willing to move it.
If you feel that this gives up too much, we could send the Philly (early 2nd) pick instead. If you think it's too little, add the Philly 2nd rounder too.
