Mate i watch most swans games and i agree with u that they dont use it much anymore but it is a scourge of the game developed by them and to scycotic who says that someone else would have used it, true but the swans were the first.
Look at swans games from an impartial position and u will see that they play boring football, it may almost always be a tight contest but there is little excitement in the way they play. Look at Carlton, its a pleasure to watch them play. As jorge valdano famously said in relation to swans fans 'if u hang a piece of shit from a rope, they'll tell u that its art but its not, its just a piece of shit (said in relation to liverpool but definetly applies in this situation). All i'm saying is that they play boring football, and being devoted swans fans u cant clearly see how boring it really easy
