Football is a simple game with many systematic complexities. We talk about these complexities, from position responsibilities to offensive and defensive schemes, and sometimes we may not fully know the specifics of what we are discussing. Bettering our understanding of the game is where our Phinsider Football 101 series comes into play. Maybe you have followed football for years, maybe you are just now learning the game. Whatever the case, there may be a term or a scheme that you don't fully grasp. We try to help by breaking down these complexities, making the game make a little more sense and hopefully helping you better understand what you are watching.
