Pacific Coast Hockey Association
Quick Summary
The Pacific Coast Hockey Association (PCHA) was a professional ice hockey league formed in 1911 by Joseph and Frank Patrick. It was a rival to the National Hockey Association (NHA), the precursor to the NHL. The PCHA introduced several innovations that improved the game, including allowing goalies to dive, dividing the ice into three zones with blue lines to change the offside rule, and introducing the concept of assists. They also were the first league to use numbered uniforms. The league faced challenges during World War I, and in 1926, the Patrick family sold their teams to the NHL, contributing to the league's expansion into the United States.12
