What's with this Nets and Mavs trade?

First George wants to back out, now the trade might be off because Stackhouse was yapping about resting for 30 days after his buyout and waltzing back into the Mavs lineup? I'm starting to think the Mavs are going nowhere fast. How will Devon Harris perform knowing he was/is trade bait? How will George perform knowing the fans hate him for being a block, and how will management treat Stack, now that he basically threw a wrench in the whole deal?
