There are only two factors preventing an individual team from finishing undefeated in the Football Bowl Subdivision.

One is statistics: The odds of perfection decrease as more games get added to the road to the national championship — and as illustrated by Alabama in 2016, the last game is always the hardest.

The second is history. In the past decade, just four Power Five teams have completed a perfect season: Alabama in 2009, Auburn in 2010, Ohio State in 2012 and Florida State in 2014.

But finishing the regular season unbeaten? Maybe that’s another story.
