  body of his opponent to cover the terri¬
  tory between him and centre, and to en¬
  able him to get out and back up tackle, or
  that will put him through back to back
  with his man before runner reaches the
  line. The latter alternative is seldom
  realized, except by a very active man fac¬
  ing a very poor opponent.
  Get up into the line. Keep your man
  at arm's distance. Watch the ball, and go
  through with it. Go through on as small
  an arc of the circle as possible, so as to not
  make holes for the other side. Don't let
  your opponent hold you. A guard should
  have at least two or three ways of break¬
  ing through. He should size up the man
  in front of him at once, and determine
  which is the most effective method to use
  in getting through.
  Try getting hold of the outside arm and
  pulling your opponent inside, so as to
  make him cover the ground between you
  and centre and leave you to back up tackle.
