The question is not what they want, it's what other offers they're likely to get.
What is the actual market?
Are the Pelicans bold enough to keep AD heading into next season if another team won't meet their preferred price?
I agree that it makes sense for the Pelicans to demand Brown and Tatum, especially since neither has solidified himself as a clear cut future star.
I'm not sure another team is really going to be able to offer the Pelicans a better package than one centered around Brown or Tatum plus a boatload of picks.
Is there any chance Philly offer Simmons? I'm not sure Embiid and AD really makes sense, as crazy as that combo would be in terms of talent and size.
I could see the Pelicans having more interest in a package built around Bradley Beal. I'm not sure if the Wizards have enough additional stuff to throw in to make that enticing. Besides, without Beal the Wizards have nothing on their roster so there's no chance they would be able to keep AD after next year.
The Clips could offer SGA, Harrell, Shamet, and perhaps some cap relief. Is SGA really more exciting than Tatum? Is Harrell good enough to make up the difference? I'm not sure.
