Before I break down these two trade ideas let me explain why I think this is the way to go. There is a lot of debate about whether or not the Bulls should "tank." I think it needs to be stated that no players or coaches would, or ever should lose games on purpose. That being said, it is management's job to determine the long and short term future of the franchise and whether it is prudent to take a step back in the short term for greater returns in the long term.
The Bulls are not winning anything this year. With the new repeater tax provisions the Bulls should do everything they can to avoid paying it in what is essentially a lost season. Furthermore, Deng's and Boozer's future after this season were going to be up in the air after this season anyway. If the Bulls trade both of them for expiring contracts, Deng could still return to the Bulls as a free agent this summer. Boozer was likely to be amnestied after this season anyway with Mirotic waiting in the wings. However, the greatest benefit of moving them now is to sacrifice this season (which has already been lost) for a higher pick in this loaded draft.
Deng to the Spurs for Diaw, Bonner, de Cola and their 1st rounder.
I can't think of a better fit for Deng, and the Spurs should be willing to give up a late first rounder for an all-star to make a run at a championship.
Boozer to the Rockets, Asik to the Bobcats, Gordon and Portland's 1st rounder (via Bobcats) to the Bulls.
Asik is hardly playing in Houston, and his trade value has diminished. Boozer and Howard are good friends, and their games complement each other. The Rockets are in a win now mode and Boozer could be the piece that makes them serious contenders. The Bobcats don't seem to want to endure another horrible season with the signing of Al Jefferson and their inspired play thus far. Their coach is a Thibs disciple and Asik would fit in well.
I would be in favor of moving Dunleavy too if the right situation came along.
Heading into next year the Bulls still have a core of Rose, Butler and a formidable front line in Noah and Gibson and the impending arrival of Mirotic. They'll have their own likely lotto pick, S.A.'s late first rounder, Portland's late first rounder, and the Charlotte pick sometime in the next three years. Additionally, they'll have about 12 million in cap space to work with this summer (same as if they let Deng walk and amnestied Boozer).
