User catching is probably one of the most effective ways to beat both man and zone without having to use a certain play. All it is is holding or tapping Y or Triangle. Tapping it allows for a better catch animation and chance of catching it, but its all about timing. Holding it allows you to not worry about messing up by tapping it, but it slows your player down as you hold it. If you can learn to be great at user catching, you can easily beat man or zone.
