If Boston landed the #1 pick I wouldn't be surprised if DA didn't try to pull a deal like that off.
Davis could be frustrated with the teams performance, and they are in a worse FA spot than Boston as of right now.
You give Simmons and the Dallas pick along with Nets '17,'18, Rozier, Sully, Young and even AB, thats a good restart for NO. They wouldn't get a better restart package than that, maybe a better player, but not restart.
