The Bulls did it. They traded Luol Deng to the Cleveland Cavaliers for Andrew Bynum, three draft picks and the right to swap first round picks with Cleveland in 2014, pending protection. Here's a full breakdown of what Chicago is receiving:
In exchange for Deng, the Cavs send Chicago Bynum, Cleveland’s right to the Sacramento King’s first round draft pick conveyed in a June 30, 2011 deal, the right for Chicago to swap its own 2015 first round draft pick with the Cavs own 2015 first round draft pick (only in the case that the Cleveland 2015 first round draft pick is between 15 and 30) and the Portland Trail Blazer’s 2015 and 2016 second round draft picks acquired from the Trail Blazers via 2013 draft night trade.
The protections on that Kings pick look like this:
Sacramento's 1st round pick to Cleveland protected for selections 1-12 in 2014, 1-10 in 2015, 1-10 in 2016 or 1-10 in 2017; if Sacramento has not conveyed a 1st round pick to Cleveland by 2017, then Sacramento will instead convey its 2017 2nd round pick to Cleveland protected for selections 56-60 (if this pick falls within its protected range and is therefore not conveyed, then Sacramento's obligation to Cleveland will be extinguished)
Plenty more on this tomorrow.
