Robben dive from yesterday

Has anyone actually realised that had Cahill not literally dived out of the way it would have been certain contact.

Look at it a few times, you realise there is very minor contact on his right foot, if he hadn't brought his left leg up, right next to his left leg and high, a "normal" left leg had he not twisted would have gone straight into the player. It's avoiding action, nothing more or less. There are going to be times when a player sees an impact coming and tries to avoid it in doing so missing the player, it doesn't automatically become a dive.
Had Cahill run normally his left leg would have been caught by the one player and he'd likely have gone head first into the second player.
It's like when you have a defender who runs across sets his body throws a leg like he's going to annihilate the player with the ball then pulls out at literally the last millisecond possible, the guy with the ball braces for contact and looks like an idiot.
This is where simulation is a problem, there are loads of circumstances in which a player sensibly pulls out of a tackle or takes avoiding action. The Robben "dive" shows that sometimes the grass simply gives out, sometimes a player slips at the wrong moment. The issue is that most players can force these situations by diving or they can happen normally and punishing those who in no way attempted to dive the same as those who did dive is a very difficult thing.
THere are bad dives and they should be punished because it would stop most players attempting to dive and then the things that aren't dives but can look like them would generally not be a problem. When people get away with blatant dives the borderline ones upset everyone as well, when the blatant ones get punished and the frequency drops drastically the borderline ones aren't going to be seen as a problem.
