Bill O'Brien (American football)

On January 21, 2021, O'Brien was named the offensive coordinator and quarterbacks coach at the University of Alabama under head coach Nick Saban, replacing Steve Sarkisian, who left to become the head coach at the University of Texas at Austin.

On January 28, 2020, O'Brien was appointed as the Texans' general manager. The Texans had gone the entire 2019 season with the position vacant. During the offseason, O'Brien traded wide receiver DeAndre Hopkins and a fourth-round pick in the 2020 NFL Draft to the Arizona Cardinals for running back David Johnson, a 2020 second-round pick, and a 2021 fourth-round pick, a move that was heavily criticized.

Following a 0–4 start in the 2020 season, O'Brien was fired by the Texans on October 5, 2020. O'Brien finished his tenure in Houston with a 52–48 (.520) regular-season record and a 2–4 (.333) playoff record for a combined record of 54–52 (.509).

On January 13, 2018, O'Brien received a four-year contract extension. In his fifth season, the Texans bounced back and finished atop the division with an 11–5 record before losing in the Wild Card Round for the second time in four years, this time to their division rivals, the Indianapolis Colts, 21–7.

O'Brien's fourth season marked his first season as an NFL head coach in which his team did not finish with a winning record. The Texans ended with a 4–12 record, losing nine of their final ten games. This season saw the debut of quarterback Deshaun Watson, whom the Texans selected in the first round with the 12th overall pick in the 2017 NFL Draft. However, Watson's season was prematurely ended after he suffered a torn ACL in practice prior to Week 9, which along with injuries to various other players contributed to the team's collapse.

In January 2013, O'Brien interviewed for the head coaching position with the Cleveland Browns and Philadelphia Eagles. However, he decided to remain at Penn State, stating: "I'm not a one-and-done guy. I made a commitment to these players at Penn State and that's what I am going to do. I'm not gonna cut and run after one year, that's for sure."

After Houston Texans head coach Gary Kubiak was fired on December 6, 2013, multiple reports stated that O'Brien was interested in returning to the NFL. On December 29, he met with the Texans for further discussion about the Texans' head coaching job. O'Brien was officially introduced as the Texans' head coach on January 2, 2014. The Texans had finished 2–14 in 2013, and owned the first overall selection in the 2014 NFL Draft, which they would use on South Carolina defensive end Jadeveon Clowney.

The Patriots gave the Jacksonville Jaguars permission to interview O'Brien for their head coaching vacancy during the Patriots' playoff bye week; O'Brien was scheduled for an interview, but never actually interviewed for the job. Instead, O'Brien interviewed with Penn State staff on January 5, 2012, was offered the head coach position, and signed a four-year contract to become the Nittany Lions' coach. O'Brien continued as New England's offensive coordinator through Super Bowl XLVI.

O'Brien was hired as Penn State's 15th head football coach, replacing Joe Paterno, who had coached the team from 1966 until his dismissal in 2011. He was introduced as the head coach at a press conference on January 7, 2012.

Due to the Penn State child sex abuse scandal, on July 24, 2012, the National Collegiate Athletics Association (NCAA) sanctioned Penn State with a four-year postseason ban, and loss of 40 scholarships over a four-year period.

I was then and I remain convinced that our student athletes are the best in the country. I could not be more proud to lead this team and these courageous and humble young men into the upcoming 2012 season. Together we are committed to building a better athletic program and university".

In his first game as Penn State's head coach, the Nittany Lions lost to the Ohio University Bobcats, 24–14. O'Brien's first win as the Penn State head coach took place on September 15, 2012, with a 34–7 win against the United States Naval Academy at Beaver Stadium, University Park, PA. Despite the fallout from the Jerry Sandusky scandal, his first season as coach at Penn State was far more successful than anticipated and resulted in a final record of 8–4. O'Brien collected the most wins for a first-year head coach in school history and was awarded Big Ten Coach of the Year on November 27, 2012.

O'Brien was named the Big Ten Coach of the Year by both the media and the coaches. On December 8, 2012, O'Brien was named the national coach of the year by ESPN. On January 17, 2013, O'Brien was awarded the 2012 Paul "Bear" Bryant College Coach of the Year Award.

After two seasons with Duke, O'Brien was hired by the New England Patriots on February 27, 2007 as an offensive assistant. On February 21, 2008, O'Brien was promoted to wide receivers coach. He became the quarterbacks coach and offensive play-caller following the 2008 season after the departure of quarterbacks coach and offensive coordinator Josh McDaniels. He was promoted to offensive coordinator in February 2011.

As offensive coordinator at Duke in 2005 and 2006, his teams averaged 16.1 and 14.9 points per game. In 2006, QB Thaddeus Lewis threw for 2,134 yards with 11 TD.

In 2003, he left to coach running backs at the University of Maryland, where he spent two seasons. In 2003, RB Josh Allen ran for 922 yards with 8 touchdowns while Bruce Perry ran for 713 yards and 6 touchdowns.

From 2001 to 2002, O'Brien served as offensive coordinator and quarterbacks coach and was named an assistant head coach for the 2002 season. In 2002, O'Brien was hired as Notre Dame's offensive Coordinator before George O'Leary was dismissed. As offensive coordinator at Georgia Tech in 2001 and 2002, his teams averaged 31 and 21.5 points per game, respectively as the teams went 9–4 and 7–6. In 2001, running back Joe Burns ran for 1,165 yards with 14 touchdowns and quarterback George Godsey threw for 3,085 yards with 18 touchdowns. In 2002 under Chan Gailey, running back Tony Hollings ran for 633 yards with 11 touchdowns and wide receiver Kerry Watkins got 1,050 yards and 5 touchdowns.

He then coached the Yellow Jackets' running backs from the 1998 season through 2000 season. In 1999, running back Sean Gregory ran for 837 yards with six touchdowns. In 2000, running back Joe Burns ran for 908 yards with 12 touchdowns.

O'Brien began his coaching career in 1993 at Brown University before spending more than a decade coaching in the Atlantic Coast Conference (ACC). He joined the New England Patriots in 2007, where he eventually served as quarterbacks coach and offensive coordinator in 2011. In 2012, he was hired by Penn State to take over a program that had just endured the Penn State child sex abuse scandal. In his first season as head coach, he led the team to an 8–4 record and won ESPN's National Coach of the Year award. After the 2012 season, O'Brien garnered significant interest to return to the National Football League (NFL) as a head coach and interviewed with both the Philadelphia Eagles and the Cleveland Browns. O'Brien decided to stay at Penn State, citing that it would send a poor message to leave after just one season. After his second season, he left Penn State to become the head coach of the Texans.

O'Brien's first coaching position was at Brown, where he coached tight ends in 1993 and inside linebackers in 1994. He then spent the next three seasons (1995–1997) as an offensive graduate assistant at Georgia Tech.
