The success of an Oklahoma football coach is not just measured in terms of overall wins and losses or all-time winning percentage, it also matters a ton on how the team performs against the Sooners' big rivals.
Every college football coach will tell you that the most important game on the schedule is the next game. At Oklahoma, however, that statement may only be partially true because all opponents are not considered equal. Wins are always going to be important, but they are valued even more at Oklahoma when they come against Texas, Nebraska and Oklahoma State.
Seventeen of the 23 head coaches in Sooner football history had winning records at Oklahoma, but only eight of the 23 produced a winning record against OU's three chief rivals.
