If I'm Zion I pull an Eli Manning to San Diego type "I'm not going there" campaign. Absolutely refuse and force someone like the Knicks to move up. I don't think anyone has that power anymore though.
I see one way the Pelicans win their post-AD with a Happy Zion situation:
Trade away AD to the Knicks. Get mega assets like the Knicks/Mavericks picks and DSJ or Knox. Use the #1 pick on Zion, use the #3 pick on RJ Barrett.
Holiday, DSJ, Barrett, Zion, Randle. I mean, not bad for NO which is not a free agent destination. Then you have other assets like Knox and the Mavs picks. Again, not bad.
I think they will be able to get better packages than that for AD. I'd ask for all that but both Knox and Smith as well as Mitchell Robinson from New York. If the Lakers will move their #4 pick plus Ingram, Hart, Kuzma and Ball that probably tops that. See if Boston will move Tatum + picks and maybe Hayward as an intriguing add on if you think he will really bounce back this season. Get crazy, ask Philly if Simmons is available. Don't get an offer you like, take your shot on selling Davis again now that you suddenly have a much brighter future.
