That data completely leaves out certain things. For example, in football and baseball, the number is virtually unchanged. So, no more or less kids are playing it, right? It's more stark than that.
There are over 40,000 more male soccer players in that data. Do you think a soccer player is a more - or less - capable overall athlete? Soccer and lacrosse are taking skilled, fast players from other sports. Football and baseball are getting watered down talent-wise because of it.
Also, I used to run a large soccer club in Ohio. We grew the club from 18 to 72 teams in 6 years, and it's only the 3rd biggest club in Cincinnati. Almost all new city and county sports complexes feature many more soccer and lacrosse facilities than baseball fields. In fact, long term plans have been modified in several counties to eliminate new baseball fields from the plan and add soccer space.
Believe me, baseball as a primary American sport is on the way out. Sure, it may be a hit in many cities at the college and MLB levels for years to come, but the US is not producing most of the top talent anymore.
