How Many Undefeated NFL Teams Are There?

As the NFL season enters its final weeks, there are still four teams with a chance to finish the regular season undefeated.
The New England Patriots, Pittsburgh Steelers, Los Angeles Rams, and New Orleans Saints all have a shot at going 16-0.
But history shows that it’s extremely difficult to finish the season undefeated, as only seven teams have done it in NFL history.
So which team has the best chance of joining the ranks of the undefeated this season?
