While a strong preseason record doesn't guarantee regular season success (e.g., 2008 Lions and 2017 Browns went 4-0 in preseason but 0-16 in regular season), no Super Bowl champion in the 11 years leading up to 2019 had a losing preseason record. Winning Preseason Week 3 has shown a correlation with 23% more regular season wins and 63.33% of playoff teams being Week 3 winners.
