The New England Patriots’ 20-year dynasty was built on some pretty simple principles. One of those was not shooting yourself in the foot by keeping easily avoidable mistakes and mental errors at a minimum.
The Patriots were pretty good at this between 2001 and 2019, and as a result won six Super Bowls. They also ranked near the top of the league in one key statistic basically year-in and year-out: turnover differential.
Fast forward to Year 3 of the post-dynasty (i.e. post-Tom Brady) era, and you see a different team — one that has had a harder time staying on the plus side of turnovers.
