Marty Schottenheimer
In 21 years as an NFL head coach, Schottenheimer won 200 regular season games and 5 out of 18 games in the postseason. He had only two seasons with more losses than wins in his entire career, and none until his 15th season; the Browns finished with a losing record in his first season, but with Schottenheimer as their coach, they were 4–4. He is the only coach in NFL history with at least 200 wins that has a losing playoff record.
