The Pelicans desperately need a center, and while his value has definitely take a hit, Vucevic is at least a viable option at center.
The Clippers should blow it up in my opinion, but it doesn't appear that they are ready to do that, so if they want to add talent Ingram is available and they likely wouldn't have to give up much.
For the Bulls, they get off Vucevic and get a 1st out of the deal
