So playing with the ESPN trade machine, I can make the above concept work but it would take 5 teams and 13 players (in other words it would tie for the largest trade in NBA history with the Miami deal that brought Shaq to Miami).
On the link you need to use your imagination because Ilyasova can't be included for another 5 days hence all those Bucks heading to Toronto but their salary equals just a few thousand over $7.9M. Also Trade Machine does not allow 5 teams. Also Minnesota can take on Gasol and a player who makes less than $854k sending out Pek/Williams/Ridnour/Lee. Finally, Gasol plus player making less than $854k going to MIN and Calderon/Bargnani going to Lakers .... so with that said:
http://espn.go.com/nba/tradeMachine?tradeId=asgwczv (and throw some picks around: Memphis 1st back to them from MIN? Raps 2nd rd to Lakers?)
Minnesota: Gasol, Jamison
Bucks: DeRozan, Wroten, Lee
Grizz: Dunleavy, Williams, Ridnour
Lakers: Calderon, Bargnani
Raptors: Gay, Pekovic, Ilyasova
DeRozan, Calderon, Davis, 2nd rd
for
Gay, Ilyasova, Pekovic
Would you?
