The Laca discussion regarding diving is interesting. When you run around the pitch your whole mentality is to not lose the ball at all costs.
It's actually quite hard to then say I'm going to turn into a sack of potatoes and fall over at any thought of anyone grazing my toe. This is also why certain cultures are often so good at diving - they grow up doing it and learn how to anticipate the smallest of contact just like they would any other skill.
At the top level of football that I have played, this whole diving thing was extremely hard. Countless times after being pushed in the box, or virtually tripped over and muscling out a shot anyway you're jogging back to halfway thinking shark, I could have gone down there.
The solution to me is pretty simple, start giving fouls without players having to fall over.
I love the simplicity of the football laws but, while a finger nail grazing a shoe lace is enough to make a fully grown athlete fall to the ground and is technically a penalty (because there was contact) - I think the governing bodies need to have a good hard think about whether the smallest of touches should be a foul or not. Which is why I don't think the VAR will help the situation at all - if anything it will make it worse as the slow-motion nature of VAR exemplifies the tiniest contact.
