I suspect that's Phoenix's play-- Ayton for Turner in a sign-and-trade deal.
I'm guessing Indiana is attempting to add Hield and grab some more young talent or wing help.
Speaking of, how about this three-way deal?
Miami trades Duncan Robinson to Indiana and receives Jae Crowder from Phoenix.
Phoenix trade Ayton and Cam Johnson to Indiana and Crowder to Miami.
Indiana trades Tuner and Hield to Phoenix and receives Ayton and Cam Johnson. They also receive Duncan Robinson from Miami.
That gives Indiana Ayton, Cam Johnson, and Duncan Robinson for Turner and Hield.
That gives Phoenix Tuner and Hield at the expense of Ayton, Crowder, and Johnson.
That gives Miami Crowder and it costs them Robinson.
