I sincerely hope that you are 2 years old.
I do not see it happening. Soccer is just too boring to attract NA masses over the long haul. I think it's already reached its peak.
What an odd thing to say.
a.) I love baseball, but baseball is significantly more boring...and the sheer amount of downtime in American football leads to it being seen as boring by many younger people too.
b.) What is there possibly to suggest that soccer popularity in this country has reached its peak? It's been growing exponentially for two decades and each new team, even in the low levels, is attracting fans at an impressive level. FC Cincinnati, an expansion third division team in a city that nobody could have seen as a soccer hotbed, keeps topping 20,000 in attendance in what is effectively a minor league.
It is very hard for any North American sports league to compete with European soccer leagues on the global stage because of the time zone where they are. For example weekend EPL games usually start between 1pm and 5pm UK time which is morning in America and evening in Asia. You can easily watch those games live almost everywhere on this planet.
I do think part of the reason the MLS is at its most popular is on the west coast is because those daytime European games come on in the middle of the night on the west coast.
FWIW I think suggesting that the MLS won't even exist 20-30 years down the road is nothing short of asinine. The financial rules in it that are presently keeping it from taking off are the rules that have allowed it to grow roots and steadily grow in popularity. They've done everything that the NASL didn't do in the name of long-term health and the growth of the game so that it wouldn't
just be teams based in New York and LA that have any hope of attracting talent. The NASL was a failure for a multitude of reasons, but the biggest was clearly that a couple teams were so dominant that the non-huge markets couldn't hope to compete, when you can't hope to compete you're going to have trouble building a fan base from scratch, and when you can't attract fans you either move or fold. You can make the joke that the MLS is expanding too fast if you want, but they've been careful about it. All-in-all there have been 3 failed teams in 2 decades of the MLS, two of which didn't really survive infancy in Florida and another that failed because of a racist ownership group that is being replaced by an expansion team in a couple years (Chivas USA -> LAFC). Compare 23 franchises in 20 years, 20 of which are still active, to the NASL which started out with 17 teams, sunk to
5 after a single season, eventually grew back to 24 despite numerous franchises folding and moving along the way, before falling to 9 teams just 5 years later before the league eventually died...and all of this happened within 17 seasons.
It is also worth noting that despite generally playing in massive NFL or college football stadiums, the NASL's best average attendance was 14,440 per game...which is lower than every single team in the MLS last year despite most teams playing in stadiums that only hold ~20k. The lowly Colorado Rapids had the worst attendance last season while playing in front of 87% capacity crowds.
MLS attendance is 8th in the world and is only about 800 fans per game away from being 5th.
