His name is Walter Camp, and he is considered to be the father of American football.
Walter was a student at Yale College from 1876-1880.
At Yale, he excelled at rugby and developed a passion for the game.
Rugby (with a dose of soccer) was the starting point for American football.
Rugby rules began to shift and change, and eventually an entirely new game was created.
Camp is credited with innovating the following rules and procedures:
Snap-back from center
System of downs
The point system
The line of scrimmage
Official field size
These new innovations revolutionized the game.
If you love football, spend a moment to thank Walter Camp.
