How to stop screen passes
The way a screen pass works is that the offensive line that's supposed to block the defensive lineman and linebackers instead let them break through and come straight for the quarterback. At this point, the running back, wide catcher, or tight end that the play is set to get the ball to will quickly bypass defenders and should be open for you to throw it. Screen games are best used as a surprise maneuver when the opponent blitzes each game, but it can also be deadly if you don't know how to stop it.
First of all, the area you're going to want to focus on here is in the apartment. This is where the pieces usually end and you want someone to be there and ready. If you're playing a typical Cover 3 defense or something like that, the defenders will come too far back and leave too much room for the player who gets the screen at least once. That's why you want players to cover the dish on at least one, preferably both sides. They may still be able to get around you, but that will at least generally slow them down.
Another option for trying to stop screen passes is to switch to a man defense. Zone defense depends on the specific coverage of certain areas of the pitch, but human defense will ensure that each player is responsible for one of the other attacking players on the opposing side. Using human defense, there will be a player specifically designated to follow the player the QB is also trying to get onscreen. It's also not a guarantee if they can get past the defender, but it does force them to be more on their toes.
