I despise Maggette but have always liked Bynum. The Cs should have kept him when he was in camp years ago. He and his HS teammate Tony Allen are both tough minded guards that really compete.
Last night, Bynum singlehandedly held back a furiou Heat comeback attempt by throwing on a Superman cape and hitting all kind of pull up jumpers and drives to the hoop. he's make a great backup PG/microwave type off the pine.
Maggette makes sense as an expiring contract. Dallas is praying that someone will take Marion's $9m salary next season so they can make a run at two max FAs (D Ho and CP3). Ship Maggette's contract to Dallas and take back Marion, and the Cs now have a roster that can better compete with the Heat. An added benefit would be to weaken both LA teams if CP3 and Howard sign with the Mavs this summer.
Dallas sends Marion to Boston and a pick to Detroit and gets Maggette's expiring $10m contract.
Boston sends Green and Lee to Detroit and get Marion and Bynum
Detroit loses Mags and Bynum and get Lee and Green along with a Dallas draft pick.
You might have to tweak this trade with some flotsam to get it to work money wise, but it makes sense for all three teams.
Boston gets two tough guys, a solid backup PG in Bynum, on an expiring deal, and a defensive minded Marion, who can play all three front court positions. A lineup of KG, Marion, PP, AB and RR would be amazing defensively, and would also space out the floor quite nicely. Boston's rotation all of a sudden makes a lot more sense.
Dallas gets the cap space they desperately need this summer.
Detroit gets two relatively cost controlled players with ability at both ends. green might not be the best fit with Prince and Jerebko already on the roster, but would be a better trading piece than Maggette this summer (after building up his value putting up meaningless numbers in a low pressure situation in Detroit, something that fits Green well).
