Post Playmaker is a new badge for NBA 2K22 and it boosts the effectiveness of both shots and moves when playing in the post. It is in the playmaking category of badges.
Post Playmaker seems to work pretty well when you actually play in the post, either by taking shots or passing out of the post. However, there are not many players that actually utilize the post seriously in games.
Recommendation: We only recommend this badge for serious post players, and at the highest level, but it really has limited use outside of that. Some big men with decent post stats may benefit from having this on Bronze, but otherwise it is not needed.
