The Football League, founded in 1888, is often regarded as the world’s first formally structured league tournament. It was once made up of 12 clubs from the north and midlands of England, and Preston North End was the inaugural winner of the Football League Championship.

In today’s football defence, multiple games and formations are used in a single game. Defensive linemen can number from three to five. The amount of linebackers on the field may alter as well. Furthermore, several teams play a nickel defence, which employs five defensive backs in passing situations.
