Hold down L2/Left Trigger and then press Square/X when a teammate is streaking to the basket.
Has anyone had any luck calling plays in mycareer? I have on court coach but whenever I bring up the menu and push a button to call a play, it doesn't work. Depending on the button I press my player will just act like the playcall menu is not up. For example, when I press Square to call a horns play, my SF just shoots the ball.
