While there a few college football rules that stand out as strange and unexpected, the most obscure one is undoubtedly the 'one point safety' rule. Below you will find an outline of college football's most odd rule.
The one point safety rule is an extension of the regular safety rule, in which the defense is granted 2 points and possession of the ball if an offense player is tackled inside of his own end zone (touchdown area). If a defensive player manages to gain possession of the ball while the offense extra point kick (worth 1 point following a touchdown) and fails to get out of the endzone before being tackled by a member of the kicking team, the offense/kicking team is awarded a point.
Part of the reason the one point safety rule is so strange is because it is highly unlikely for the kicking team to mess up an extra point so badly that the defense has a chance to secure the ball and try to run it back for a touchdown. Although it is unsure how one point safety rule came out, the overall consensus is that the stipulation was enacted to add excitement to an otherwise boring aspect of college football, as it gives both the offense and defense a chance to score following a blocked extra point kick.
