This trade doesn’t change either team much. Mitch has experience playing with quickly and Barrett which helps Toronto. 4 picks is solid. Precious is an expiring contract.
Poetl could start but won’t. Instead either he or McBride is first off the bench. In the playoffs, the Knicks often go 7 deep. Poetl and McBride in this role would be nearly ideal. As for depth, after the starters it’s Payne/Deuce/Shamet/Poetlwith Kolek/McCullar/Dadiet/Hukporti/Sims. Sims could still be moved for picks or Wing depth
