This is a really good opportunity for the Bulls really. They can now have justification to trade away Deng, Noah, and/or Boozer. I think Noah and Boozer will be the go to moves.
If I was the Bulls, I would trade Deng and Boozer to Golden State for Barnes, scraps and Lee. Deng would be good for Golden State because it would give them defense and a low post threat. It was pretty obvious Lee isn't one. Deng is a defensive minded SF that knows how to win. Chicago would get Lee, who they could use this summer if they wanted to for trades, or just keep him for rebounding.
Then I would work out a deal with us, like Denny mentioned, sending out Noah for Claver, Barton, Leonard and Freeland or T. Rob.
This would make them younger and bad enough to probably get a top 5 pick. Using Charlotte's pick, their own and maybe even grabbing another pick via trade could make them go getters in this strong draft.
When Rose gets back, he will have a young nucleus of solid players for the next go around.
