As I understand it, the word "warrior" in the sports world usually refers to the Golden State Warriors, a professional basketball team based in San Francisco, California, USA, that competes in the NBA (American Professional Basketball League).
Founded in 1946, the Golden State Warriors are one of the founding teams of the NBA and played in Philadelphia in their early days. In 1962, the team moved to San Francisco and changed its name to the Golden State Warriors. Between 1971 and 1982, the Warriors changed their name to the Golden State Samurai, but reverted back to their original name after 1982.
The Golden State Warriors are a powerhouse in the NBA and have won multiple championships. The team has famous players in its history such as Rick Barry, Oxlade-Chamberlain, Thurmond and many more. In the late 2000s and early 2010s, the Warriors experienced a period of slumps, but gradually rose to prominence as a powerhouse in the NBA after 2010. In 2015, the Warriors defeated the Cleveland Cavaliers 4-3 to win the championship. In 2017 and 2018, the Warriors won the championship again, becoming the first team in NBA history to win more than 70% of the regular season in a single season.
Apart from basketball, the term "warrior" can also refer to other sports teams, such as American football, baseball, etc. Which team is specific needs to be determined according to the type of sport.
