BYU basketball boasts an impressive record of conference success during its history. BYU has claimed a conference championship trophy (regular season or tournament) during 30 seasons. The Cougars won the 1991 WAC Tournament after a second-place regular-season finish. Other conference tournament titles in 1992 (WAC) and 2001 (MWC) have followed up regular-season rings, as was the case with conference playoff wins in 1924 and 1933 in the Rocky Mountain Conference. BYU won six Rocky Mountain Conference titles in 20 years, earned five Skyline championships in 24 years, recorded 12 WAC crowns in 37 years and garnered MWC titles in six of the league’s first 12 seasons. BYU won the in-state title against rivals Utah and Utah State during 10 of the 12 years before the Cougars first joined a conference in 1918.
