The Miami Dolphins had a perfect season and went undefeated, than lost their second game the next season to have a winning streak of 18 games!
As of now, December 2011, the defending champion Green Bay Packers also have an 18 game winning streak... and counting.
The Green Bay Packers also owned the NFL's first undefeated season and championship in 1929.
