Some rules in football when changed proved how stupid the old rule were, League games and a good few Cup finals were played with 11 players against 10 due to injury.
When the substitute rule was introduced I can still hear the die-hards lamenting the change, not too mant complaints now, change can be good for the game and the boring offside law is one change I would like to see, defenders getting praise for moving forward as one man to slow the game down, boring, get it changed.
