It doesn't require Mikal or Ayton to get salaries to work but it would require Craig and Shamet also being included and then you're talking 5 for 1 but I would imagine Brooklyn would throw in some minimum salary guys so they didn't have to waive them like Nader when he was included in the CP3 deal.
Of course if you're Phoenix then you do that deal, a bunch of role players for KD is a no brainer but I doubt Brooklyn would bite. Perhaps Brooklyn has more interest in DA now that they could acquire him and wouldn't be hard capped like a sign and trade would do. There was talk that is why they didn't want DA and not necessarily his talent. Being hard capped for a year would hurt a team like Brooklyn that doesn't operate like there's a luxury tax because they're in a major market and don't need to worry about things other teams do.
