This feels a bit like a publicity stunt to be honest.
Will be interesting to see how it works in practice. There are obviously some clear cut dives where punishment is fair enough, but there's also a lot which fall in to a grey area where you can't reasonably tell if a player has deliberately dived or whether what seemed like minimal or even no contact actually did cause them go to ground. You often hear commentators accusing someone of diving because there was no contact but the player has lost their balance in avoiding getting clattered. How will they handle stuff like this?
