              BETWEEN THE 20S
        Once you reach the third section of the playing field between the 
        20 yard lines, you can introduce variety and creativity to your
        play calling. Your offensive unit is out of danger: no longer
        vulnerable to a safety. You can mix up your play calling, avoiding
        predictability by using formations that confuse the defense, and
        generally become more aggressive.


              THE DEFENSE'S 20 TO THE 5 YARD LINE
        When you reach the opponent's 20 yard line, you've entered the
        fourth section of the field. Now, you're able to complete medium
        passes into the end zone. The defense usually goes into man-to-man
        coverage in the heart of the field, so you get to experiment with
        some pass plays that are effective against this kind of coverage.
        In some ways, though, you should be more cautious here than in the
        middle of the field. You have entered field goal range, and don't
        want to give it up by attempting high-risk plays that get you 
        pushed back out of field goal range.
