It is a sport entirely for children here.
Well... I mean, that makes total sense.
Maybe the most fun game in the world to actually be playing and maybe the most boring sport in the world to be watching, in my opinion, it makes perfect sense that the only people interested in it are the people playing it and the people who are forced to show up with them because they're kids.
Pong can be fun to play, too, but man is it dull to watch, you know?
Back... bounce bounce... forth... bounce bounce... back... bounce bounce... forth.
Americans ultimately need sports with lots of intermediate statistics because we're stat-heads and we love measuring up performances against each other. At the end of the day, the only significant stats in soccer are... shots on goal and goals made. Did the player kick the ball in or not, did the goalie block the ball going in or not? Everything else is just, like, people kicking a ball around.
Football has yards and attempts and passes and all sorts of neat stats between scoring and not-scoring that you can crunch and weigh and debate. Baseball's got hits and extra base hits and walks and strikeouts and averages and ERA and onbasepercentages and all sorts of other things to yammer about. Basketball, not so much, but there's so much scoring to be done that we can make other stats from it.
But soccer and hockey, the two sports that keep trying to woo America and never pull it off... you got shots made, shots missed and MAYBE assists and... that's it. America wants numbers, America wants mile-markers, America wants two pages of numbers explaining the gradual steps between victory and defeat so that we can pick them apart and discern the patterns.
If you give us "Yeah, they tried ten times to score, one guy did, the other guys tried fifteen times, two did... and the rest of it, dudes were kinda kicking something around for a while" we're gonna glaze over. I don't know what this says about American psychology, but there we are.
