I wish they would use the videos to detect and punish simulation. There will always be some borderline cases, but where a player is untouched (or touched in a completely different area) and then kicks off, hurtling to the ground while screaming in agony, and then jumps up as soon as the play resumes.
The game would be better without so much focus and time spent on playing to trick the referee. Having teams that are more evenly matched as ever and adding more penalties without addressing simulation will make for a boring game in the end that is just a contest of whoever can fool the referee better to get an advantage.
Unsporting behaviour can already get a player cautioned (and therefore a second such offence can already get a player sent off) and attempting to deceive the referee is literally the first example of unsporting behaviour given in the rules. It's strange that this isn't used more often, particularly in matches where certain players are frequent offenders.
In other situations, like putting the ball out so an opposing player can receive medical care, every player understands that this is just good sportsmanship. Likewise no-one criticises a player from that opposing team who gives possession back to the team who put it out when play restarts. So why are players who all respect that tradition OK with people who frequently take a dive or appeal for something they know they don't deserve?
