Boise State began their streak following a loss to Washington State in 2001. Following that defeat, the Broncos accumulated the top home winning streak in the nation (and one of the best in college football history) with 31 wins in a row. A Humanitarian Bowl win in Boise over Iowa State of the Big 12 Conference is included in that streak but is not counted in the regular season home streak. A season-ending loss to Boston College in the 2005 MPC Bowl ended the overall streak. The Broncos have now won another 28 straight regular season games at home.
Included in Boise State's 58-0 record in the regular season is a 4-0 mark against schools from Bowl Championship Series conferences. Boise State is 4-0 against Pac-10 teams, 36-0 against Western Athletic Conference foes, 5-0 against teams from the Mid-American Conference, 1-0 against Conference USA, 1-0 vs. I-A Independents, 2-0 against the Sun Belt, 3-0 vs. the Mountain West and 6-0 against I-AA or FCS teams.
Eight schools since 1869 have recorded 50 straight regular season home wins. Five of those did it prior to 1916. In the modern era, the Broncos are one of only three schools to achieve 50 straight regular season wins at home.
Princeton holds the NCAA record with 75 in a row from 1887-1900. Miami of Florida (1985-1996) is the modern leader with 69 straight. The Hurricanes won 58 in a row at home until an Orange Bowl loss to Nebraska in 1994 (which was in the postseason). They won 14 straight home games following that defeat but three were in Orange Bowl wins.
Carlisle, which was victorious in 52 straight from 1901-1915, and Pennsylvania, which also won 52 straight from 1889-1896 are tied for the #5 all-time position. Michigan had its origin of what we now know to be an outstanding tradition in 1901, reeling off 50 in a row until a home loss to Pennsylvania in 1907. Yale also put together 50 straight home wins from 1886-1895.
Of course, the 2005 MPC Bowl loss to Boston College in Bronco Stadium is counted as a postseason home game. The Broncos are in the all-time top 15 for an overall 50-game home record of 49-1.
