I’ll start by saying I don’t like soccer and don’t pay attention to it. But I have no problem with scoring all the goals you can in World Cup play. There are a bunch of good reasons to;
1- Goal differential matters
2- It is the pinnacle of these player’s careers. They shouldn’t have to throttle their play.
3- There is no mercy rule and apparently substitutions are limited. That is the governing associations problem to address.
4- If you wanna run with the big dogs you’ve gotta get off the porch. I mean I feel some sympathy for Thailand because they are clearly outclassed on the WC stage but that is how sports work. It’s their job to get better, not our job to play down to the competition.
5- You can’t dial down at this level without consequences. They will be facing much tougher competition and you want your players at peak performance for later rounds. It’s not an easy task to get that edge back if you dial it down for an inferior opponent.
As far as the much talked about “celebrations”, imo soccer celebrations are generally all excessive and frankly, ridiculous. I probably feel this way partly because I don’t particularly care for the sport but the celebrations and crowds are over the top. It could be a nondescript game of little importance and they go absolutely bonkers over a goal. NHL hockey teams that have just won the Stanley Cup are at about 10-20% of a typical run of the mill soccer game goal. So, accepting that it is just that way in the soccer world, what the US women did was nothing. There is no reason a player should not be able to celebrate any goal or 5 goals in World Cup play. And it was obvious their celebrations were not in any way intended to taunt or make fun of the other team.
It just is what is, a much better team delivered an asskicking to an inferior opponent. Time for some people to grow up and realize there are winners and losers, especially in sports.
