They just might.
The problem is, as long as their big 3 (Deng/Boozer/Noah) are on this roster and healthy, they won't be bad enough to tank against this horrific east. The east is barely fielding any winning teams. So in order for the Bulls to tank, they'll need to unload at least 2 of the 3. I doubt anyone wants Boozer, Deng is already expiring, and I have no idea what kind of contract Noah has.
In other words, the only way I see them losing at least 2 of their big 3 is via injury. I doubt they can unload them via trades to suck like us and tank.
