During the 2019 season, the Patriots did something that nobody has done in NFL History: They held opposing offenses to less than a 25% conversion rate on third down (24.1% exactly). This is the lowest in NFL History. The previous record holder was the 2017 Vikings at 25.2% and before them it was the Saints back in 1991 (!) where they held opposing offenses to a 26.1% conversion rate.
