Soccer has funny "simulation" thing that professional players often do. It was funny until I realized from short article on it, that players have to do that when sports game turns into potentially harmful attacks. Lots of them simulate too much of course, but if they'd never do that, injuries were unavoidable. It looks like non-maleworthy clowning, but actually it saves them from partial life-long disabilities way before these happen. Expression is there only to get an attention. It has nothing to do with cheating when done at the right times.
