CHC meaning in General ?

The professional American football team now known as the Arizona Cardinals previously played in Chicago, Illinois, as the Chicago Cardinals from 1920 to 1959 before relocating to St. Louis, Missouri, for the 1960 through 1987 seasons.

Roots can be traced to 1898, when Chris O'Brien established an amateur Chicago-based athletic team, the Morgan Athletic Club. O'Brien later moved them to Chicago's Normal Park and renamed them the Racine Normals, then adopting the maroon color from the University of Chicago uniforms.

In the 1920s the Cardinals became part of a professional circuit in Chicago. The Cardinals, along with the Chicago Bears, were founding members of the National Football League in 1920. Both teams are the only two surviving teams from that era. The Bears and the Cardinals also developed a rivalry during those NFL first years.

After some irregular campaigns during the 1950s, the Cardinals were largely overshadowed by the Bears in Chicago and almost fell into bankruptcy. After some efforts to buy the Cardinals, a group of investors including Lamar Hunt, Bud Adams, Bob Howsam and Max Winter, joined forces to form the American Football League to compete with National Football League. The Cardinals would later move to St. Louis, Missouri, beginning with the 1960 season.
