The whole point of having punishments for breaking the rules is to deter players from breaking the rules. What punishment would be adequate to deter Suarez, or another player in his place, from doing the same thing in the last five minutes of the semifinal, or god forbird, the world cup final? Certainly a one match suspension isn't gonna do it. I'm thinking five at least, and probably more like 10-15 international matches. (In these instances, a ban that extends beyond the World Cup would mean the player would miss his country's following competitive games...in this case those games wouldn't be nearly as important as the World Cup games, but a large enough suspension would keep most players from pulling a stunt like Suarez). If FIFA leaves the suspension at just one game, then I suspect we could see some other teams start playing with 11 goalkeepers instead of one toward the ends of their World Cup knockout matches.
