Honestly think an issue keeping soccer from ever really catching on in America is we have no idea what a 3 vs 3 match would look like (we have a good sense of how to shrink a 5-man basketball team down for half-court 2 on 2) and we don't live in villages or even pre-automotive towns really so we never have 21 of our mates looking for something to do
it works exactly like every other sport with a net?? if there are three ppl around one can play goalie and the others defend or attack depending on whether they currently have the ball or not, etc. with more people you scale up until at like half strength you decide to use two goals and so on. I'm by no means a soccer fan but this doesn't seem like a hard concept to grasp?
This is also weird because the fact that it's so easy to play is basically the reason it's caught on all over the world, even in the poorest communities. All you need is something to kick, preferably a ball, and something to use as goalposts, where traditionally kids will use two bags or jumpers.
America isn't unique in not having kids roam around in gangs twenty-two players strong, and everywhere else seems to manage. You can easily do three people as described, two vs two, then up to things like five a side which are actual competitive formats.
Football can easy be scaled down in this way, and probably much more than baseball, ice hockey, American football which Americans seem to cope with. Hell, even basketball needs a hoop, whereas I've played so much football without a goal, and just a couple of friends (or at school you could go the other way and have twenty per side and simply enlarge the pitch).
Football sucks. That’s why the only two nations that really matter, India and China, don’t care compared to all the tiny bitch countries that nobody cares about. Hell, even the third most country in the world, the USA, doesn’t care that much about soccer.
