Not overly convinced by that Liverpool goal, I'm like 250 miles from Ewood Park and even I'm more onside than Cisse was.
I'm all for giving the benefit of the doubt to the attacking team, but this 'active/inactive' thing seems to be a cause of a lot of confusion and indeed controversy. It would make the linos job a lot simpler if all they had to do was look along the line and make a simple, instant, "YES/NO" call on whether a forward is beyond the last defender when the ball is played, rather than needing to wait around seeing where the ball goes, having a bit of think about what the player is up to and finally deciding if he is active or not.
I'm not saying that such a rule would necessarily make for the most entertainment, but at least everyone would know where they stood - less than two opposition players closer to the goal than you = offisde.
