In this trade, we imagine a scenario where the Knicks wants to move on from Randle bc of his future extension and the synergy between the team. This trade consists of sending more smaller assets like 1 pick swap in 2028 and few 2rnds with players like Sims or pacome dadiet who won’t be playing lots of minutes w the Knicks. In exchange the Knicks receive an all star pf who can shoot and be useful on defense + a center to backup Mitchell Robinson who will progress a lot under thibs. Plus in this trade the Knicks free up some cap space who can be used to sign a 1yr deal with another player for more depth. Knicks rotation after this:

PG:Brunson/Mcbride/kolek/Payne SG:Bridges/Divincenzo/Mcbride SF:Anunoby/Bridges PF:Markannen/Anunoby/Bertans C:Robinson/Kessler

For the Jazz this trade is for the future, Markannen contracts has 1yr left and you need something in return. With this trade you get 1 pick swap and few seconds who can give you chance to develop players on long term and having better chance to take while having another player with great value who will surely bring interest close to the deadline. In this situation, the Jazz give themselves better chances at landing a top pick in maybe the best draft of the next 3yrs with a few players still having great value for a trade.
