An example of OI backfiring would be closing down often a player who is very skillful. This will often result in them just taking it round the player and finding themselves in space. Also, if you set an AM to be closed down often it is usually a CB who will step out to do the closing down leaving a gap in your defence.
I use OI a lot and it certainly helps.If the opposition have a particularly weak player then set his marking to easy and they will tend to pass to him which should play into your hands.
I find OI most effective for dealing with wingers,. I always set the opponent's wingers to close down often. Also, if you are playing against tall, slow strikers then set the wingers to be shown onto their inside foot. This ensures they play the ball to the strikers' feet more often than getting a cross in. Obviously vice versa for playing against small fast strikers.
OI can be very effective if used correctly I find, especially when you are playing against teams you aren't expected to beat.
