American Football at its BEST

• Each team wants to defend the field that is
  behind it and invade the field in front of it.
• Ultimately, they want to gain enough ground to
  score a touchdown or field goal.

Football

• Game of inches
• Teams succeed based on how many yards they
  accumulate or allow
• Official NFL Football Field is 120 yards long and
  53 yards, 1 foot wide

Yard Lines and Hash Marks
Yard lines ?

• Hash marks on either side of the field mark each
  yard.
• At every fifth yard, a solid white line runs from
  sideline to sideline.
• At every 10 yards those lines are numbered (10,
  20, 30, 40, etc.).
• This crosshatch of lines gives the field its
  "gridiron" nickname.

Goal Posts
Goal Post ?

• Centered at the back of the end zone is a pole
  that extends 10 feet high and connects with a
  horizontal cross bar.
