The nation's largest youth football program, Pop Warner, saw participation drop 9.5 percent between 2010-12, a sign that the concussion crisis that began in the NFL is having a dramatic impact at the lowest rungs of the sport. According to data, Pop Warner lost 23,612 players since 2010, thought to be the largest two-year decline since the organization began keeping statistics decades ago. Doctors acknowledge that concussions are a concern, but are saying that the fear has overtaken the scientific evidence. What do you guys think? Will you be putting your kids in Pop Warner football?
