Better idea:
Celtics receive: Collins, Crowder into TE (could be Shamet, Saric, and/or Payne instead)
Celtics trade: Theis, G Williams, Nesmith, Stauskas, TE, 2024 1st
Hawks receive: Ayton (s/t max), Nesmith
Hawks trade: Collins, Capella, 2023 and 2022 1sts
Suns receive: Capella, G Williams, 2023 Hawks 1st, 2024 Boston 1st
Suns trade: Ayton, Crowder
Thunder receive: Theis, Stauskas, 2022 Hawks 1st (16)
Thunder trade: future top 55 protected 2nd
Celtics:
PG: Smart, Pritchard
SG: Brown, White
SF: Tatum, Crowder
PF: Collins, Horford
C: Timelord
That's an excellent 9-man rotation
