St George won 11 consecutive rugby league titles from 1956 to 1966, establishing an unprecedented era of dominance in the sport. This sustained success led to growing frustration among rival clubs, who struggled to compete with the team's consistent performance.
The impact of St George's reign extended beyond the field, ultimately prompting a major shift in the rules of the game. In 1967, a new four-tackle rule was introduced, aimed at increasing the pace of play and making the competition more dynamic and balanced.
