Oklahoma football: Weighing Kansas State's chances against the Sooners - Article Photos 5/10

Why OU will win 5. OU protects its house against ranked intruders: The Sooners have lost just three times at home under Bob Stoops, and those were all complete surprises vs. unranked opponents (OSU in 2001, TCU in 2005, Texas Tech in 2011). In the modern era of college football, K-State has won just three times in Norman (1970, 1994, 1997).
