Michigan's teams from 1969-1976 is the only other college football team since 1903 to win at least seven consecutive games in eight straight years.
After an early-season loss to Arkansas in 2002, Boise State put together 11 consecutive wins to close out the season, including a 34-16 win over Iowa State in the Humanitarian Bowl. The Broncos suffered an early 26-24 loss on the road to Oregon State in 2003, yet bounced back for 11 straight wins in a 13-1 season that culminated in a 34-31 victory on the road over TCU in the Fort Worth Bowl. Of course Boise State enjoyed unbeaten regular seasons in 2004, 2006, 2008 and 2009.
The 2005 team opened with road losses to Georgia and Oregon State and most teams would have gone on to mediocre seasons. Boise State responded with nine straight wins. The 2007 Boise State team fell on the road to Washington but came back with nine consecutive victories.
Princeton holds the all-time record with 21 consecutive years of winning seven consecutive games. The Tigers did it from 1883-1903. Yale is second by achieving the feat from 1886-1898. Harvard did it 10 straight years (1886-1895) while Pennsylvania (1891-1898) and the aforementioned Michigan team also had a streak of eight consecutive years.
If Boise State is fortunate enough to string together seven conseuctive wins this fall, they will break the modern record that they currently share with Michigan.
