Two other factors in the equation: There is a federal law — the Sports Broadcasting Act of 1961 — that prohibits the NFL from televising games within a certain vicinity of live high school or college games, so as not to diminish potential attendance at the latter events. Now that most high school and college schedules have winded down, there is more flexibility on the NFL’s part. Also, all 32 NFL teams have now had their bye weeks, creating more game slots for each week’s schedule.
