American football coach (born 1953)

Mark Duffner (born July 19, 1953) is an American football coach who is currently a senior defensive *istant for the Cincinnati Bengals of the National Football League (NFL). Duffner served as the head coach of the Maryland Terrapins football team from 1992 to 1996.

Duffner was born and raised in the Washington, D.C. suburb of Annandale, Virginia; he played tackle for legendary coach Bob Hardage at powerhouse Annandale High School and played collegiately at the College of William and Mary under head coach Marv Levy and was recruited to the school by *istant coach Bobby Ross. His first coaching job was as a Graduate *istant under iconic coach Woody Hayes at Ohio State University followed by a stint as Defensive Coordinator for the University of Cincinnati Bearcats; he moved to Holy Cross in the same role in 1981 and ascended to the Head Coach position in 1986, compiling a stellar 60–5–1 record. At Maryland, Duffner compiled a 20–35 record, his most important legacy at Maryland has been in the record books; most of the Terps' longstanding single game, season, and career p*ing and receiving record were broken during his tenure. This was due to the implementation of his run and shoot offense and quarterbacks John Kaleo, Scott Milanovich, and Brian *mings. However, his teams were notoriously weak on defense, frequently giving up points so fast that even his prolific offense couldn't keep up. Duffner's only winning season came in 1995 when the Terps finished with a 6–5 record and started with four consecutive wins.

After leaving Maryland, Duffner became an *istant with the Cincinnati Bengals from 1997 to 2002, where he served as linebackers coach and then defensive coordinator. From 2003 to 2005, he served with the Green Bay Packers. In early 2006, he was signed by the Jacksonville Jaguars as the linebackers coach. He was hired by the Miami Dolphins in January to be their LB Coach for the 2014 season. On October 15, 2018 Duffner was named as the new defensive coordinator of the Tampa Bay Buccaneers.

Duffner was hired by the Bengals as a senior defensive *istant on March 7, 2019. He missed the team's week 10 game in 2020 against the Pittsburgh Steelers due to COVID-19 pandemic protocols.
