International games work. They sell out, they trend, they make headlines. But a stadium event is a peak, and peaks fade. The question for U.S. leagues isn't whether Europeans will show up for one weekend — it's what they do for the rest of the season.
Fandom is built in smaller rooms: a bar in Kraków that shows the late game, a university society in Milan, a creator in Belgrade explaining the rules in the local language. These are the places where a curious viewer becomes a follower, and a follower becomes someone who buys the jersey.
The smarter strategy is city-first. Pick the places where interest already exists, map the communities and creators, and give them a reason to gather every week — not once a year.
What to do next: stop measuring international success by attendance at one event. Start measuring how many cities have a weekly ritual.
