Taking this further, youth football has only minimally changed relative to the 180s other sports have done. Sure, the very, very best kids are in all kinds of super camps all year, but even a mediocre soccer, baseball or basketball player is doing year-round club. Not really a thing in football. You play in the fall, and that's kind of it. There's lifting, but you have autonomy to do other sports.
Very typical nowadays for an 11-year-old to have to decide between soccer or baseball because of indoor/spring ball, to decide if basketball has to go in favor of wrestling, etc. I'm not saying it's good or bad, but you are probably losing some kids because their fall is taken up by some other club they're already specializing in, plus concussions, injury risk etc.
