Boozer won't be amnestied because it would cost ownership too much.
Luol Deng has value as an All-star and brings in the most when selling high and still keeps us competitive and under the cap.
It is easier to replace Luol with a combination of Butler, Mirotic, and Gibson than it is to replace Boozer with Taj.
The FO is maintaining your trade value.
Luol Deng, I love you, but the writing is on the wall.
