Been hearing this from my soccer fan buddies for 30 years.
“It’s not that popular now but just wait until….”
Yeah ok.
I've followed Liverpool for 40 years now, and I played 10 years here. But yeah, exactly this. It's not made for the typical current American fan. It probably had its best shot when we had the NASL which had legit stars in it, not as far past their prime. Back then people weren't in as much of a hurry and actually still enjoyed watching slower sports like baseball. Now the MLB is highly regionalized and viewership is still dropping. The MLS is OK, but new fans today are SSAT (super short attention span). YouTube was even getting too long for them so now it's TikTok. It's never going to catch on here, most fans like short bursts of entertainment. It's also why other slow, popular sports like Cricket will never have a shot here. If it doesn't have commercial breaks, it's probably not going to make it here.
The passion of European football is unrivaled, we don't have an equivalent here. That 2nd leg CL win vs Barca was probably the single most intense and crazy sporting event I've ever witnessed. The closest thing I've seen to a crowd reaction here was when DB scored that EN goal to sweep St. Louis. That's the absolutely loudest I've ever heard Staples, even in the cup final it didn't get close to that level. It's like that in European soccer with regularity. It's a huge social event over there and teams are a source of local pride.
I watch a lot of sports from other countries, I don't watch a lot of stuff here outside of the NHL and some NFL games. I catch some Angel and Laker games occasionally, I watched the NBA a lot more until around the early 2000's. I think one sport that might actually be able to gain a following here is Rugby. There's a running clock, so the games are really short even though they are 80 minutes. If you watch it, you know exactly what I'm talking about, it kind of flies by. It's got a lot of the things US fans like, it's physical and athletic with lots of action outside of scrums and kicks.
