wonder if we could ever get to the point where, via sensors in the ball and attached to all the players, a computer could determine offside by calculating where the ball, last defender, and runner all are relative to each other?
i don't mind technology if it can actually be painless and certain, like goal-line technology.
but it's the thought of applying it to the inherently subjective, like fouls or cards, that's so gruesome, because it will mean even more whinging about the refereeing than before, only more abstract, tiresome, and time-consuming.
