Gridiron football, namely American and Canadian football are the derivatives of Rugby football and Association football and evolved in their own directions over the long period of time in the North America.

Gridiron football (North American football)

American football fields 11 players per team while 1 team is 12 players in Canadian football. The Canadian football had more unique features before. But it’s becoming more similar to the American football since it imported some of the rules from the USA.

The common features include the use of the hard body protections such as a helmet and pads. Forward passing and downs were also invented. The Gridiron football uses smaller oval shaped ball with both ends pointed. This makes the long distance 1 hand passing possible. The Rectangular field with lines looks like the grid.
