A late hit, a disputed catch or a player’s eligibility can bring a game to a halt—but there isn’t one authority that governs every level of American football. The NFL, college football, high schools and international competitions each have their own rule-making systems. Understanding who is in charge explains why the same play can be … Read more

A defender can be in the right place, read the play correctly and still watch the ball carrier race past. That is speed’s most obvious effect in American football—but it is not the whole story. Quick acceleration, sharp changes of direction and the ability to recognize a play can matter just as much as a … Read more

A football player can look unstoppable on the first drive and still struggle to finish the game.

The NFL built its postseason by adding teams and rounds, while college football moved from bowl invitations and opinion polls to a national playoff. The … Read more
