Wendell Carter (small sample set) is considered one of the best Jokic defenders. 270 lbs and long arms - something Jokic himself has noted: https://www.sportingnews.com/us/nba/news/nikola-jokic-stoppers-lebron-james-warriors-blueprint/922de28c190d2f1dc3c5500e.
Chet needs a big strong guy to play next to him. On defense Chet can roam/help to rim protect while Carter can play more on the biggest opponent. Chet's spacing makes it possible to have both guys out there on offense.
SGA - Dort/Cason - Williams - Chet - Carter
OKC needs to move on from Giddey. His value is low but now is the time to act. Poku is out of the rotation. A 2nd sweetens the pot for Orlando, who could use a great passer like Giddey. They've been thriving without Carter somehow so this is just gravy for them.
