What sets MyCareer in NBA 2K21 the most apart from other modes is that you really have to find the smallest of edges to be successful. You don't have to give up a triple-double to receive an A + teammate rating, nor do you have to be a defensive brick wall. What can help you, especially if you're new to the series, is helping other players get noticed. Screens are a great way to do this, as you can keep the ball handler's opponents from defending them, so your teammate can go to the hoop.
Every button for every platform
However, you may have found yourself confused as to how to define them. The reason being, setting up a screen doesn't use the same commands as calling one up when you have the ball. You can call up a screen just by squeezing the right front trigger, but setting one up takes some work.
When your player is off-ball attack, go to the defender you want to filter out. Make sure you have completely stopped moving, then press Circle, for those on PlayStation, or B, for Xbox users. For Switch users, you'll want to use the A button on the joy-con.
How big is the impact on the score?
As a result, you will potentially get big bonuses to the rating of your game. There are a number of reasons for this. First, the screen itself is considered an excellent defensive game, and therefore a small increase in the letter quality bar is practically guaranteed.
Second, if you have a decent team, the teammate with the ball has to be smart enough to score an open bucket, which the game calls an “onscreen assist”. This is what you are mainly looking for. With each screen helper, your bar will fill halfway - or as much as a regular helper.
