The NFL's head injury issues are causing some parents of youth and high school football players to rethink whether football is safe enough for their children.
No link has been established between parents' safety concerns and football's popularity, though there are indications that fewer kids are putting on pads.

The recent suicide of former NFL star Junior Seau hit home for Elizabeth Giancarli, who decided to keep her 7-year-old son Jason in flag football instead of letting him start tackle. She says: "I just don't know if it's worth it."
