Joe Gibbs is the only coach to have more than one tenure. Two different coaches have won NFL championships with the team: Ray Flaherty in 1937 and 1942, and Joe Gibbs in 1982, 1987 and 1991. Gibbs is the all-time leader in games coached and wins, and Dudley DeGroot leads all coaches in winning percentage with .737 (with at least one full season coached). Mike Nixon is statistically the worst coach the Redskins have had in terms of winning percentage, with .182.
