This works in the Trade Machine:
Tatum, Hayward, Williams, Yabu
for
AD, Hill, Moore
Key question is why would the Pelicans take on Hayward?
Well, there's good reason to think he might return to something like his previous form.
It would help if he has some nice moments over the remainder of the season and in the playoffs.
Whether the Pelicans want to remain halfway decent, or they flip Hayward for additional assets another year or so down the line, he wouldn't necessarily be a negative part of the deal.
I'm certain the Pelicans would prefer the rumored offer using Smart or Horford as salary filler, but if I were the Celts I'd try to sell the Pels on Hayward.
Here's hoping Hayward has some big games over the next few months.
