There’s a difference between diving or faking and exaggerating, do they both merit the same punishment?
Imagine kicking a chair on accident, you can’t do anything but wince in agony for a few seconds. A lot of these incidents where someone is really hurt for 5-10 seconds and then gets up are more like that than faking. Even guys who go down with cramps when they’re 1-0 up in the 95th minute, there’s no way to determine if it’s legit or not.
