The trade order:

OKC packages 30 and 34 to move up to 24 with the Bucks (could be anyone in this range).

OKC packages 12 and an early 2023 2nd rounder to get Grant for SAC. DET would then have picks 5 and 12 to play with (either to draft or package in a deal with HOU to move up to 3).

OKC trades:

Grant (from DET), Dort, Pick 24 (from MIL), and the rights to Vasilije Micic (https://nba.nbcsports.com/2022/05/29/report-two-time-euroleague-finals-mvp-vasilije-micic-wants-to-come-to-nba/) for Pick 4 and takes on Holiday's salary (redundant, need to free up money to retain/extend their guys).

OKC then would take two of Holmgren, Smith Jr., Banchero, Ivey to add to their core of SGA and Giddey.

(If OKC needs to give SAC more here, they can swap the Bucks with the Bulls and offer Kenrich Williams and picks 30 + 34 to CHI for 18 and give that to SAC)

(If OKC needs to give DET more here, they can add a 2023 late first from DEN)
