Philadelphia Eagles Callahan started his NFL career as the offensive line coach for the
Philadelphia Eagles from 1995 to 1997.
Oakland Raiders Callahan then spent four seasons as the
Oakland Raiders' offensive coordinator before being named the franchise's 13th head coach prior to the 2002 season. In his first season as a head coach, Callahan led the Raiders to a third consecutive AFC West title and the franchise's first
Super Bowl since returning to Oakland, making him just the fourth rookie head coach in NFL history to do so. The Raiders suffered a lopsided defeat in
Super Bowl XXXVII losing 48–21 to the
Tampa Bay Buccaneers coached by his former boss
Jon Gruden. It did not help that the Raiders were without starting center
Barret Robbins, the leader of their offensive line. Robbins went into a manic episode after not taking his medication, and spent most of the day before the game in
Tijuana believing that the Raiders had already won. When he finally resurfaced, Robbins was so incoherent that Callahan had no choice but to leave him off the roster. Callahan is the third Raiders head coach to win an AFC West title and lead his team into the conference championship game in his first full season. Only
Art Shell (1990) and
John Madden (1969) had accomplished this feat. Under Callahan's guidance, the Raiders led the NFL in passing for the first time in team history and led the league in total offense for just the second time in team history. During his tenure as not only head coach but also offensive coordinator for the Raiders, the Raiders offense led the league in rushing in 2000 and led the league in passing in 2002. In 2002, the Raiders became the first team to win games in the same season while rushing at least 60 times (against the
Kansas City Chiefs in a 24–0 shutout victory) and passing at least 60 times (against the
Pittsburgh Steelers in a 30–17 win). The Raiders offense also set many franchise records during this period, including fewest sacks allowed (28) in 2000, a mark that was broken the following year (27). Despite the success of the 2002 team, the Raiders had a losing record in 2003. After they got off to a 2–5 start, many of the players, in particular
Charles Woodson, publicly criticized Callahan, even suggesting that Callahan was deliberately trying to "sabotage the season". According to Woodson, the Raiders locker room was almost in a state of mutiny against Callahan, a claim corroborated by veteran receiver
Tim Brown and others. Callahan, his supporters claim, had recognized that the team was aging and needed younger talent. To get it, he would have to cut existing salaries, an assertion that did not sit well with many of the team's veterans. It did not help that quarterback
Rich Gannon was sidelined with injuries for much of the season. On November 30, after a 22–8 loss to the
Denver Broncos, Callahan said the Raiders must have been "the dumbest team in America in terms of playing the game." After a lackluster 4–12 season, Callahan was fired by Raiders owner
Al Davis. Although the Raiders had gone all the way to the Super Bowl a year earlier, Davis was not known for being patient with his coaches. Callahan was the last Raiders head coach to post a winning season until
Jack Del Rio in
2016.
Controversy surrounding Super Bowl XXXVII In January 2013, Callahan was publicly accused of sabotaging
Super Bowl XXXVII by several former players. According to comments by
Tim Brown and others, the Raiders struggled on offense during the Super Bowl because of Callahan changing the game plan from a heavy run attack to a heavy passing one on the Friday before the game. Although some claim this was due to the Barret Robbins incident, Brown offered no proof for the sabotage claim, but said: "this is the problem we have, because of Callahan's relationship with Gruden, because of his disdain for the Raider organization; that's what makes people get to that conclusion."
Jerry Rice, an NFL Hall of Famer who was a wide receiver for the Raiders at that time, was quoted as saying, "I was very surprised that he waited till the last second and I think a lot of the players they were surprised also so in a way maybe because he didn't like the Raiders he decided 'Hey look maybe we should sabotage just a little bit and let
Jon Gruden go out and win this one.'" Callahan has denied the allegations, stating that, "While I fully understand a competitive professional football player's disappointment when a game's outcome doesn't go his team's way, I am shocked, saddened and outraged by Tim Brown's allegations and Jerry Rice's support of those allegations made through various media outlets over the last 24 hours. To leave no doubt, I categorically and unequivocally deny the sum and substance of their allegations." Callahan further referred to the claim as "ludicrous and defamatory."
Nebraska Cornhuskers Soon after being fired by the Raiders, Callahan was hired at the University of Nebraska–Lincoln. This would mark the first time in over four decades (since the hiring of
Bob Devaney in 1962) that the Cornhuskers would be led by a head coach with no direct ties to the university either as a player or an assistant coach. In his first season at Nebraska (
2004), Callahan finished 5–6, giving the Cornhuskers their first losing season in more than 40 years. He had introduced the
West Coast offense to a program that had traditionally relied on a strong
option running attack. The Cornhuskers finished 8–4 during his second season and won the
2005 Alamo Bowl by defeating No. 20
Michigan, 32–28. The 7–4 Wolverines were the highest-ranked opponent that Nebraska had defeated since a 20–10 win over No. 2
Oklahoma in October 2001. The Wolverines also were the highest-ranked opponent defeated by Nebraska away from home since a 66–17 win over
Northwestern in the
2000 Alamo Bowl. The
2006 team finished 9–5 and won the Big 12 North for the first time since 1999. The win over then No. 24-ranked
Texas A&M marked Nebraska's first ever road win over a ranked Big 12 South team. Many expected that the 2007 season would be a breakthrough year for Nebraska. However, the team fell well short of expectations. Nebraska was beaten by
USC 49–31 in a nationally televised September 15 game, being outrushed by a 313 to 31 margin but outgaining USC in the passing game 389 to 144. A 41–6 thumping by
Missouri started a five-game losing streak—the Cornhuskers' first since 1958. On October 15, 2007,
Steve Pederson, the athletic director who had hired Callahan, was fired. Pederson was replaced on an interim basis by Nebraska's legendary former head coach,
Tom Osborne. On November 3, the Cornhuskers suffered a 76–39 pounding at the hands of
Kansas. It was the most points a Cornhuskers team had ever surrendered at the time. The Cornhuskers followed this performance a week later with a win, scoring 73 points against
Kansas State. On November 24, 2007, the day after a 65–51 loss to rival Colorado, Callahan arrived at the team's practice facility at 6:30 a.m. He met briefly with Osborne and was fired. While leaving the complex, he waved to reporters gathered outside. Osborne announced during a press conference held at the school that despite Callahan's ouster, he would still earn $3.1 million as part of his buyout. While Nebraska's defense struggled during Callahan's tenure, numerous offensive school records were set (some of which could be attributed to the dramatic change in offensive philosophy) and quarterback
Zac Taylor was named Big 12 Offensive Player of the Year for 2006. Callahan's tenure as Nebraska's head coach was primarily defined by an emphasis on recruiting (something many Nebraska fans felt was lacking during the previous coach's tenure). For example, with the assistance of his recruiting coordinator John Blake, Nebraska recruited defensive tackle
Ndamukong Suh (2009
AP Player of the Year,
Nagurski Trophy winner,
Heisman Trophy finalist, etc.) although Suh later stated that he would "probably be at Oregon State right now" had Callahan not been fired. Callahan's 2005 recruiting class was rated as top-five by Rivals and ESPN analyst Tom Lemming said they were "No. 1, without a doubt.". Despite a 27–22 record, Callahan's tenure is considered to be a failure. He led the Cornhuskers to two losing seasons in four years. Callahan also finished ranked in a major poll only once in four years after the Huskers had only finished unranked once since 1962. Streaks such as 35 straight years in a bowl game and decades of consecutive wins against Kansas were lost in his four-year tenure. Callahan was 3–10 against teams ranked in the Top 25, 27–2 in games in which he led at halftime, 0–17 in games in which he trailed at halftime, 25–21 against Division I opponents, 15–18 against the Big 12, and coached the program its only two losing seasons (out of 4 seasons at Nebraska) in 46 years.
Sports Illustrated named Callahan as the worst coaching hire of the decade in college football. Exacerbating Cornhusker fans' consternation with Callahan's tenure at the university was his insistence that he had "done an excellent job in every area."
New York Jets On January 18, 2008, Callahan was hired as assistant head coach of the
New York Jets. On January 2, 2009, he interviewed for the position of head coach of the Jets. In 2008, three of the offensive linemen (with Bill Callahan as their position coach) from the Jets were named to the Pro Bowl:
Nick Mangold,
Alan Faneca, and
D'Brickashaw Ferguson. All three repeated in 2009. Under Callahan's direction of the running game, the Jets broke the franchise record in 2009, gaining 2,756 yards on the ground through 16 regular season games. They led the National Football League in rushing and averaged 4.5 yards per attempt. For the 2009 season,
Peter King named Callahan the assistant coach of the year.
Dallas Cowboys The
Dallas Cowboys hired Callahan as their offensive line coach during the 2012 offseason. On June 4, 2013, Cowboys owner
Jerry Jones announced that Callahan would call plays on offense during the upcoming season, allowing head coach
Jason Garrett to focus on game-management. After being the offensive coordinator for the Cowboys during the 2013 season, Callahan was stripped of his play calling duties. During the 2014 offseason, the
Cleveland Browns and
Baltimore Ravens both asked the Cowboys for permission to interview Callahan for their open offensive coordinator positions, but the Cowboys declined. The Cowboys let Callahan's contract as offensive line coach expire after the 2014 season, allowing him to seek other opportunities. At the time, Callahan was considered among the best offensive line coaches in the NFL, and some considered him to be the leading reason behind the success of the Cowboys' offensive line, which had three linemen (
Tyron Smith,
Zack Martin, and
Travis Frederick) named to the
2014 All-Pro Team.
Washington Redskins On January 15, 2015, the
Washington Redskins hired Callahan as their offensive line coach. On March 15, 2017, the Redskins promoted Callahan to assistant head coach in addition to his offensive line duties. On October 7, 2019, following a 0–5 start to the season, the Redskins fired head coach
Jay Gruden and named Callahan the interim head coach for the rest of the season. Callahan went 3–8 in his stint as interim coach. The Redskins hired
Ron Rivera shortly after the conclusion of the season.
Cleveland Browns On January 31, 2020, Callahan was hired by the
Cleveland Browns as their offensive line coach under new head coach
Kevin Stefanski. He missed the Wild Card Round against the
Pittsburgh Steelers due to
COVID-19 protocols, but returned for the Divisional Round against the
Kansas City Chiefs. On January 20, 2023, Callahan nixed an offensive coordinator interview that he had with the
New York Jets and agreed to a contract extension with the Browns.
Tennessee Titans On February 13, 2024, Callahan was hired by the
Tennessee Titans as their offensive line coach to work under his son,
Brian, who was hired as the team's new head coach a few weeks prior. After the Titans fired his son on October 13, 2025, Callahan left the team the following day.
Atlanta Falcons On January 18, 2026, Callahan was hired by the
Atlanta Falcons to be their new offensive line coach, reuniting him with new head coach Kevin Stefanski. ==Head coaching record==
