I think we are giving up too much. Holiday is never going to be healthy. Ryan Anderson has had terrible injuries in the past and Omer Asik is a negative asset (in order for a team to absorb his contract they would need to attach an asset to Asik).
I'd much rather add to the veteran trio on cheap contracts (Thomas, Bradley, Crowder) than deal one of them.
The pelicans are a good trading partner though.
