if the Celtics sign and traded Crowder and Jackson to the Jazz after releasing Mickey and stashing Yabuselle then they could sign a free agent prior to the Jazz sign and trade transaction to the tune of about $6,254,691 in the first year. If we traded Crowder to other team for no salary we could sign a free agent for $5,338,691 in the first year and then sign Hayward as a free agent, i think the celtics are looking to make another minor free agent signing, and naturally exploring the possiblitly of maximising to possible cap room by involving Utah.
btw in both sceranio the Celtics would retain the room exception.
It would make sense to me that the for Celtics to replace Crowder on the current roster perhaps with a free agent like Ilyasova or Beasley, who we may be able to sign to a similar contract, and be a better fit next to Hayward
