You can still do it but they made it a real pain in the ass to choose the player. You gotta press L1, then R1 (Positional playcalling) then pick the player, then choose what you want them to do. Massive stuff up in my opinionThe AI is so s**t defensively in this game, constantly over switching and leaving players open.
Also why the hell can't I select a player off ball to bring up plays for them? 2k19 you would hit L1 and then whatever position to get them coming off a screen or cut to the basket. Now it's replaced with a clusterfu** of random plays.
