High school football kicked off this past week across Ohio with fewer kids on the field. A study from the National Federation of State High School Associations shows the number of kids playing football declined for the second year in a row – down by about 50,000 over two years. The study also says, however, that football remains the most popular boys' sport. WKSU commentator Terry Pluto said football can be beneficial for kids, if it’s approached the right away.
