In Part 4 of the NFL Network’s “Health of the Game” series, Andrea Kremer looks at the lack of consistency regarding safety standards in youth football leagues across the country. The absence of common safety standards in youth football makes it very difficult to enforce uniform safety rules.

Kremer speaks with players on a Massachusetts-based Pop Warner football team that recently saw five of its players suffer concussions in a single game. Kremer examines the challenges facing children who want to stay safe while playing football and whether parents should allow their kids to play.
