The MMQB looked at the best teams in league history over at least a 12-year period, and here were the interesting findings about where the Patriots of 2001 to 2016 rank with them: a New England’s regular-season winning percentage of .766 over these 16 seasons is the best of any team in league history in a span of at least 12 years. a New England has won 14 division titles in those 16 seasons, the highest rate of division/conference titles won by a franchise over that span.
