The 1972 Miami Dolphins went undefeated both post and regular season but back then only played a 14-game NFL season

The 2007 New England Patriots went 16-0 and are the only team to go undefeated in a 16-game NFL season

The 1984 San Francisco 49ers, the 1985 Chicago Bears, the 1998 Minnesota Vikings, and the 2004 Pittsburgh Steelers all went 15-1.
