Adjusted idea that assumes that Hayward wants to go to Indiana. The narrative here would be that Hayward wants to go to Indiana, but Ainge is unimpressed with the possibility of Myles Turner coming back to the Cs in a return.
Indiana: Hayward
Celtics: Collins, 6, 30 million dollar trade exception
Hawks: Oladipo, Edwards, 14, 30
This move does right by Hayward which reflects well on the Boston franchise. But it also gives the Hawks another ball-handler to fit next to Trae Young. It also keeps the Hawks as a potential free agent destination in the 2021 off-season, because Oladipo is an expiring.
The Celtics then move forward with the plan from the original post. They draft Hayes or Haliburton at 6. They trade 26 and the trade exception (with Robert Williams?) for Steven Adams. They sign a shooter to the full MLE (Gallinari, Harris, or Bertans).
