Call a timeout during a game and go to your coaching settings. Then, change the defensive pressure all the way up and help defense all the way down. That way, your players won't sag off on bit, they'll be face-guarding them. Second off, if you want to steal more passes, I would consider setting up in a halfcourt man or a halfcourt trap. I wouldn't recommend full court because that will fatigue your players quite rapidly. Now, when the ball is in the air, press X to change your player. That will most likely switch you to the player the ball is going to. While it's in the air, direct your thumbstick towards the ball and press square which is, obviously, the steal button. You can also hold your right thumbstick upward to raise your arms and contest the passes. Last but not least, intense defense. Hold down L2 while your user controlled player is guarding the ball. This is intensify that players defense, and will make it twice and hard for the offensive player to dribble drive on you. Hope I helped, man!
