Of the other dynasties: Pittsburgh won in 1974 with a 10-3-1 record The Niners won in 1988 with a 10-6 record, only getting in the playoffs on tiebreakers after finishing in a 3 way tie for first in their division. (2 other NFC teams finished 10-6 and didnt make the playoffs) The Packers won in 1967 with a 9-4-1 record. The Cowboys won their 3rd of the 90s after changing coaches. The other dynasties have won the SB in seasons with less than impressive regular seasons (Dallas was 12-4 that year so maybe they dont count). I think it is part of the Patriot legacy to rise above a so-so regular season and run the table.
