History and Purpose
In the earliest days of American football, offenses were allowed to shift and assemble themselves as much as they wanted, much as defenses do. The famous Notre Dame Box relied heavily on these shifting motions. However, rule changes were eventually implemented that prevented offenses like the Notre Dame Box from ever occurring again. The motion rules seen today resulted from these rule changes. Currently, wholesale formation shifts can only occur before the offensive formation is set, and said formation must be in place for at least one second before a snap or motion can occur.
The purposes of motion are to allow the offense to change formations and, in leagues that allow forward motion, a chance to gain momentum on the defenders.

Famous quotes containing the words history and/or purpose:
“History is more or less bunk. It’s tradition. We don’t want tradition. We want to live in the present and the only history that is worth a tinker’s damn is the history we make today.”
—Henry Ford (1863–1947)
“To me the sole hope of human salvation lies in teaching Man to regard himself as an experiment in the realization of God, to regard his hands as God’s hand, his brain as God’s brain, his purpose as God’s purpose. He must regard God as a helpless Longing, which longed him into existence by its desperate need for an executive organ.”
—George Bernard Shaw (1856–1950)
