Brian Callahan in 2021 enters his 12th NFL season, and his third in Cincinnati. He joined the Bengals as offensive coordinator prior to the 2019 season.

In 2020, Callahan helped transition rookie QB Joe Burrow, the No. 1 overall pick in the draft, to the pro level despite the absence of an in-person offseason program due to the COVID-19 pandemic. Callahan helped Burrow to one of the most productive starts to a career by a QB in NFL history, before a knee injury ended the rookie's season after 10 games. Still, Burrow's 264 completions were the most ever by an NFL QB through their first 10 career games, while his 404 pass attempts were second and his 2688 passing yards were fifth.

In 2019, his first Bengals season, he helped steer the offense to significant improvement despite the absence of several key players due to injuries. In the rushing game, Cincinnati's per-game average jumped 70.6 yards from the first half of the season (59.5) to the second (130.1). And in the passing game, each of the Bengals' top four WRs — Tyler Boyd, Alex Erickson, Auden Tate and John Ross III — posted career-highs in both receptions and receiving yards.

Prior to his arrival in Cincinnati, Callahan was quarterbacks coach for the Oakland Raiders in 2018. In Oakland, he helped QB Derek Carr to a career-high 4049 passing yards, a 93.9 passer rating, and an AFC-best 68.9 completion percentage.

Prior to his season in Oakland, Callahan was quarterbacks coach with the Detroit Lions from 2016-17. Over the course of his two years in Detroit, Lions QB Matthew Stafford ranked in the top-10 among NFL passers in TD passes (53), passing yards (8773), completions (759) and completion percentage (65.5).

In 2017, Stafford ranked third in the NFL in passing yards (4446) and fourth in passing TDs (29), while throwing a career-low 10 INTs. In 2016, Callahan's first in Detroit, he helped Stafford to an NFL-best eight fourth-quarter game-winning drives, the most by a signal caller in a single season since the 1970 AFL-NFL merger.

Callahan entered the NFL as a coach with the Denver Broncos, spending six years with the club in a multitude of offensive roles. He entered in 2010 as a coaching assistant, then moved to offensive quality control from '11-12, offensive assistant from '13-14, and offensive assistant/quarterbacks coach in '15.

During his run with the Broncos, Callahan helped mold one of the NFL's most potent offenses, which led the Broncos to five consecutive AFC West titles from 2011-15, including a Super Bowl 50 victory in 2015.

Callahan also helped the Broncos' offense to four consecutive seasons (2012-15) of 4000 passing yards. Denver's QB during Callahan's tenure was future Hall-of-Famer Peyton Manning, who during his time as a Bronco won the NFL MVP award (2013), two AFC titles ('13 and '15) and a Super Bowl title ('15). Callahan in 2013 helped the Broncos' offense to one of the top offensive seasons in league history, including an NFL-record 55 TD passes from Manning, an NFL-record 606 points, and league-best 457.3 yards per game (second-most in NFL history).

Callahan served as a coaching assistant with the Broncos in 2010, his first season as an NFL coach, but he was thrust into a more extensive role with the team's running backs after mid-season coaching staff changes.

Prior to joining the NFL coaching ranks, Callahan spent two years (2008-09) at Junipero Serra High School in nearby San Mateo, Calif., as the team's offensive coordinator and QBs coach. He broke into the coaching ranks from 2006-07, as a graduate assistant at UCLA — he served in football operations in '06, and then worked with the WRs in '07.

Callahan played collegiately at UCLA, where as a former walk-on QB he appeared in 13 games as a holder on PATs. He earned a bachelor's degree in sociology from UCLA in 2006, and a masters in education in '08.

The son of former Raiders head coach (2002-03) Bill Callahan, Brian Callahan was born in Champaign, Ill., but attended high school in California in the Bay Area. He was a two-year letter-winner at QB at De La Salle High School in Concord, Calif., where he was a part of the school's national-record 151-game winning streak and led the team to a No. 1 national ranking. Callahan and his wife, Allyson, have a son, Ronan, and daughter, Norah.
