4 Team Trade. Only team that likely says No is Boston.
Boston receives Pau Gasol, Kyle Lowry, and TE for $6 Mill.
Denver receives Rondo, Bass, Terry, and Earl Clark
Lakers receive Gallinari, Calderon(Expiring), and Mozgov(Expiring)
Raptors receive Lawson, Brewer(Expiring), and Collins (Expiring)
For Boston it's a win now deal. They think Lowry, Bradley, Pierce, KG, and Gasol with a bench of Sully, Green, Lee, Barbosa, and Wilcox can go all the way.
For Denver they get the best player in the deal in Rondo. They feel Rondo, Chandler, Igoudala, Fraried, and Koufos with a bench of Miller, Terry, Mcghee, and Clark/Randolph can do some damage.
For the Lakers they get a D'Antoni favorite in Gallinari. He fits the system perfect at PF. They also get expiring deals in Calderon and Mozgov to lessen payroll next season.
For toronto they get an upgrade at PG over the two they're sending out. He just signed a long term deal and he is young enough that he fits real well with their rebuilding efforts. They also save $8 million in payroll this season and both Brewer and Collins are expiring deals.
Edit: See Alternative deal below if you don't think Toronto upgrades with Lawson over Lowry.
