Which NFL coach has the best playoff winning percentage (min. 10 games)?

Vince Lombardi has the best NFL playoff winning percentage among coaches with at least 10 postseason games, going 9–1 for a .900 mark.

Lombardi coached the Green Bay Packers from 1959 through 1967 and briefly led Washington in 1969. His playoff record was built almost entirely with Green Bay, where his teams became the dominant force of the early 1960s.

The Packers won five NFL championships during Lombardi’s tenure, including the first two Super Bowls after the 1966 and 1967 seasons. They also won three consecutive league championships from 1965 through 1967. Lombardi’s only postseason defeat came against the Philadelphia Eagles in the 1960 NFL Championship Game.

The minimum-games condition matters because coaches with only a few playoff appearances can post a perfect percentage without a comparable sample. Lombardi’s 9–1 record covers 10 games, making his .900 figure the standard answer rather than a small-sample anomaly.
