The trouble with saying that someone should be sent of for an “obvious” violation of the rules is that obvious violations of the rules happen every game, every league, all the time. How often is there a picture of an attacking and defending player, both going for the ball, one with his hand on the other’s shorts, while the other has a fistful of the first player’s jersey? Push, pull, jump at, kick, trip, etc. happen all the time. Fortunately for the game, or maybe unfortunately, no league enforces the rules as written.
As a teacher, I am well aware that the broader goal of managing the situation is what controls what one does in the way of “enforcement.” I, too, have the ability to “send off” a “player” (student) for telling me to “fuck off.” Depending on the situation, I might well do that. But if I can get the student to realize that’s not acceptable, without sending him off to the principal’s office, where he will be written up and suspended, thus missing school, isn’t that preferable? After all, the goal isn’t to enforce rules. The goal is to have a good game (in my case, by educating all my students as much as possible).
Different leagues have different flavors of play. This has always been the case, and always, God willing, will be. It should not be the case that we see the same soccer in Argentina that we see in Italy that we see in England. That’s part of what makes the World Cup so interesting: we get to see the clash of styles and wonder which style of play will win the day. But since EVERY league is having to decide exactly what level of tolerance it will have for activity on the field that violates the Laws, the bar will be different from league to league.
It’s been known for decades that the English game is a more physical game. This doesn’t translate to a more negative game, if you measure that by goals scored. As my statistic quoted last time shows, the Italian and English games are scoring at roughly the same rate this year; indeed, the English teams are managing slightly more goals per game. Are there times when we see obvious fouls go unpunished? Yes. But in Serie A, there are times when people are punished for having done nothing. Which is preferable? I know which I prefer, which is why you see much less diving and rolling around in the EPL than you do elsewhere. Hell, even Ronaldo has learned the lesson there.
I don’t mean to make you think I’m rubbishing your underlying desire. I recognize that you want two things: you want to see “beautiful” soccer, soccer like it was when the Hungarians were playing it in the 50s, or like the Brazilian teams of Pele played. You also dislike drawn games. That latter dislike is a trait you share with the overwhelming majority of American sports fans (which is why I think Americans are generally idiots when it comes to sports). In answer to your two valid themes I say these two things: first, don’t conflate these legitimate desires with what appears to be a tendency to engage in loose thinking to trash what you don’t like, and second, consider that soccer was always MEANT to have both drawn games, and defensive play. The better process for enjoyment may be to learn to appreciate both, as they happen.
After all, in the end, the point to the league is to do the best you can, not to score a lot of goals, or play beautiful soccer.
