Although every season starts out with the goal of winning every game, the reality is, unless you are one of the truly elite teams — and even if you are — the odds of going undefeated through 12 or more college football games are heavily stacked against you.
To show you how rare it is, Oklahoma has gone undefeated and untied for a full football season just 11 times in its storied 125-year history. And in three of those years, prior to 1900, an entire season consisted of just two games.
It has been 19 years since the last Sooner team registered a perfect season: the 13-0 2000 national championship team.
