Key metric: High School Sports Participation

Let me tell you something - this story is a GAME-CHANGER! We're witnessing a MAJOR SHIFT in the playbook of high school sports, folks! Flag football for boys is like a wildcard team entering the playoffs - it's shaking up the whole league! These young athletes at Lick-Wilmerding are showing the heart of champions, adapting their game to stay on the field. But make no mistake, they're in a tough scrimmage against the JUGGERNAUT that is traditional football culture. The NFL, like a seasoned coach, is trying to draw up new plays to keep the game alive at all levels. But here's the kicker - they're facing a FOURTH AND LONG situation with the boys' high school demographic. It's a classic matchup of safety versus tradition, and right now, it looks like a defensive slugfest with no clear winner. This could go into overtime, folks!
