Of all the people to have carried the rare surname Chedgzoy, the most famous by some distance is Sam Chedgzoy, an Everton and England footballer remembered not just for how he played, but for changing the laws of the game.
The player
Born in Ellesmere Port, Sam Chedgzoy was an outside-right (a winger) for Everton, where he made well over 300 appearances. He earned 8 caps for England between 1920 and 1924. By any measure he was a fine top-flight player. But that is not why his name survives in football trivia.
The loophole
In 1924 the laws were changed to allow a goal to be scored directly from a corner kick, where before another player had to touch the ball first. Sam Chedgzoy, or someone advising him, read the new wording carefully and spotted that it did not actually say the corner-taker could not play the ball again himself.
The stunt
So in a match at Goodison Park, instead of crossing a corner he dribbled the ball in from the corner flag, all the way toward the goal, while players and the referee looked on in confusion. He had not broken the new rule as written. The point was made.
The rule change
The authorities promptly closed the loophole. The law was amended to say the player taking a corner cannot touch the ball a second time until someone else has played it, which is exactly the rule still in force today. In other words, a Chedgzoy is directly responsible for a line in the modern laws of football.
