ARSD meaning in Sports ?

The American Roller Skating Derby (ARSD) was a professional roller derby league. As of 2012, the ARSD consisted of six teams: the San Francisco Bay Bombers, the Los Angeles Firebirds (formerly the San Diego Firebirds), the Chicago Pioneers, the Brooklyn Red Devils, the Eastern Chiefs (aka the New York Chiefs) and the Orlando Thunder. Most trained and competed in the East Bay area (near San Francisco, California), but one team, the Firebirds, was based in Escondido, near San Diego.

Unlike leagues in the past, the ARSD invested in building a new track, and new uniforms. Ferrari made arrangements to have the tracks up at different venues for additional training, and in some cases, for a week or more at a time. The league also used former skating stars Delores "Tillie" Tucker, "Bad Boy" Alphonso Reyes, Larry Lewis, "Mizz" Georgia Hase and Jim Fitzpatrick as coaches and mentors during these training sessions. Dan Ferrari died December 14, 2016, and the league has since disbanded.
