This is roughly the system employed by the NFL, and it works fairly well. Coaches can challenge a number of calls per game (2, I think?) and are penalized with losing a timeout if their challenge turns out to be invalid. I don't know if there is an equivalent penalty that could be leveled at a soccer team for an invalid challenge.
>lying doesn't matter, it's just expressing emotions. you almost never see a referee backing up from a decision, more often discussions result a yellow card.
Lying matters to some people - good sportsmen for example. When I played (only amateur: Uni/Sunday league) I'd tell the ref if he'd made a wrong decision in my favour.
IMO lying is not a proper part of [association] football; that's why I gave up on footie some time ago.

> Would it really kill soccer if we had video replay?
it wouldn't if they were limited, just as switching players is. if one team had one single chance of calling for a replay, it wouldn't kill the dynamic, but would solve the problem of nonaccredited goals or the Kaka situation with Ivory Coast.
