You can't be offside in your own half so kind of negates that. I was focusing on then lettering of the law, the player has to be actively in play right? So if he runs towards the ball, he's involved in the play straight away, so it should be flagged from there not when he finally reaches a player and touches the ball. I need to re-watch the Aguero incident to see it properly but I stand by going to the point where the player initiated his intent to play rather than when he meets the ball until they specifically state that in their rules unless they have? An example I can think of is if you're offside, just inside thenopposing half and a ball is played over the top but you pelt towards it and tackle the keeper, going by the Spurs one, the offside is now down their penalty box instead of way further up the park but you involved yourself in that sequence of play well before that tackle, doesn't make sense.
