Freezeframes didn't exist last century

when the Laws of Association Football were cobbled together to introduce some order into the game. This really didn't matter a bit until technology reared its ugly head. Now the equipment has outstripped the match officials and is causing problems. The most obvious case is when television can freeze an image showing a player is not in an offside position when the ball is kicked. However, in the fraction of a second it takes an assistant to turn his head and focus on the offending player, he has moved into an offside position and the flag goes up. The only solution here is for the player to give a little bit of ground to make sure he is onside when the linesman is looking. Being level with the second last defender when the ball is kicked may tempt the linesman to raise the flag. (FIFA's website has an instructive interactive guide to offside)
