Only one NFL team has ever had a perfect season.
Other than that phenomenal team, every other squad has ended their season with at least one loss. It’s ridiculously difficult not just to go undefeated, but to sustain that level of success for any stretch of time.
Currently, after two weeks of the 2017 NFL regular season, there are only eight teams that are still perfect.
Those teams are:
Atlanta Falcons
Baltimore Ravens
Carolina Panthers
Denver Broncos
Detroit Lions
Kansas City Chiefs
Oakland Raiders
Pittsburgh Steelers
When you look at this list, you have to wonder just which one of those teams has the best chance to stay perfect, at least in the short term.
