Ok let me explain how it would theoretically work. Starting out Steven Adams is out for the season so we are eligible for another dpe (disabled players exception) so all depends if the league accepts it. It would be 7M due to it being 1/2 of the injured player's salary. Disabled player exceptions only go as far to match no further. Bulls just cut someone in this scenario by the way.

Here are the trades without picks just to explain salary

Rockets get: (18.1M)

Coby White (12.8M)

Trade 3
