You pretty much proved the point. Many people watch the league game on a weekly who were never serious football players, not just the Superbowl commercials. Every Sunday and sometimes college football Saturdays, there's a huge fan base tuning in and buying jerseys. Those 100,000 seat college stadiums aren't there because of the cheerleaders or commercials. NFL and NBA are so profittablehe bc they would never tell elite players not to play high school because they understand that their future fanbase will develop from watching stars in high school and college. Yes, soccer should be involving the high school community more, not less. Encourage cheerleaders, colorguards, or a slew of other high school groups to attend these games. Don't discourage it and shit on it. How many potential fans do you think they'll lose?
More kids play soccer and yet the fan base is way less than football and basketball. Do you know why? How does a league expect to gain a fanbase when they think they are too good for their own communities. MLS and NWSL will alienate most US soccer players, and potential future fanbase, by not letting their stars play for their high schools. Think about how many people are getting annoyed with the elitist attitudes of these leagues that are ruining their high school and potentially even college soccer teams rather than supporting these high school and college soccer teams.
