Question: What NFL coach was replaced by Dick Jauron for the Bears, and who now coaches for Tennessee?
Context: The 2003 Chicago Bears season was their 84th regular season completed in the National Football League.  The club posted a 7–9 record under head coach Dick Jauron.  The team was once again in a quarterbacking carousel with quarterbacks Kordell Stewart, Chris Chandler, and rookie Rex Grossman.  The club improved over its 4–12 record of the season before, but it was not enough to save Jauron's job. The 2001 Chicago Bears season was their 82nd regular season and 23rd postseason completed in the National Football League.  The club posted a surprising 13–3 record under head coach Dick Jauron en route to an NFC Central title and the number two seed in the NFC.  The Bears, led by Jim Miller, seemed like a team of destiny, with five comeback wins during the season, including two straight improbable wins where safety Mike Brown returned an interception for the game-winning touchdown in overtime.  However, it was not to be as the Bears were upset at home by the Philadelphia Eagles 33–19 in the NFC Divisional playoffs. The 2009 Buffalo Bills season was the 50th Professional Football season for the original American Football League team, and its 40th in the NFL.  The Bills were unable to improve upon their third consecutive 7–9 regular season record (2006, 2007 and 2008) and failed to make the playoffs for the 10th consecutive year, the longest standing playoff drought in the NFL.  Dick Jauron returned as head coach for a fourth season, the first Bills coach since Marv Levy to receive a contract extension beyond three years.  He was fired on November 17 after a 3–6 start and replaced on an interim basis by defensive coordinator Perry Fewell, who was fired at the end of the season, but not before starting Ryan Fitzpatrick for the rest of the season. Richard Manuel Jauron (born October 7, 1950) is a former National Football League (NFL) player and coach.  He played eight seasons, five with the Detroit Lions and three with the Cincinnati Bengals.  He was head coach of the Buffalo Bills from January 2006 until November 2009.  Jauron had previously held head coaching positions with the Chicago Bears and, on an interim basis, with the Detroit Lions.  He was the AP Coach of the Year in 2001 after leading the Bears to a 13–3 record. The 2000 Chicago Bears season was their 81st regular season completed in the National Football League.  The club posted a disappointing 5–11 record under head coach Dick Jauron.  The season saw the addition of rookie sensation Brian Urlacher who would win the NFL Defensive Rookie of the Year Award. Perry Fewell (born September 7, 1962) is the American football defensive backs coach for the Jacksonville Jaguars.  He last served as the defensive backs coach for the Washington Redskins of the National Football League (NFL).  Before that he served as the interim head coach and defensive coordinator of the NFL's Buffalo Bills.  He was named interim head coach after serving as the team's defensive coordinator from 2006 to 2009 under head coach Dick Jauron.  Most recently, Fewell was the defensive coordinator of the New York Giants. The National Football League Coach of the Year Award is presented annually by various news and sports organizations to the National Football League (NFL) head coach who has done the most outstanding job of working with the talent he has at his disposal.  Currently, the most widely recognized award is presented by the Associated Press (AP), although in the past several awards received press recognition.  First presented in 1957, the AP award did not include American Football League (AFL) teams. " The Sporting News" has given a pro football coach of the year award since 1947 and in 1949 gave its award to a non-NFL coach, Paul Brown of the All-America Football Conference's Cleveland Browns.  Other NFL Coach of the Year awards are presented by "Pro Football Weekly"/Pro Football Writers of America and the Maxwell Football Club.  The United Press International (UPI) NFL Coach of the Year award was first presented in 1955.  From 1960 to 1969, before the AFL–NFL merger, an award was also given to the most outstanding coach from the AFL.  When the leagues merged in 1970, separate awards were given to the best coaches from the American Football Conference (AFC) and National Football Conference (NFC).  The UPI discontinued the awards after 1996. The 1999 Chicago Bears season was their 80th regular season completed in the National Football League (NFL).  On January 24, Dick Jauron was named head coach.  The club posted a 6–10 record under Jauron, who replaced Dave Wannstedt. Michael Rene Mularkey (born November 19, 1961) is an American football coach and the head coach of the Tennessee Titans of the National Football League (NFL).  He played college football for the University of Florida, and thereafter, he played nine seasons as a tight end for the NFL's Minnesota Vikings and Pittsburgh Steelers.  He has served as the head coach of the Buffalo Bills, Jacksonville Jaguars and Tennessee Titans on an interim basis, the offensive coordinator for the Pittsburgh Steelers, Miami Dolphins and Atlanta Falcons, and the tight ends coach for the Miami Dolphins and Tampa Bay Buccaneers of the NFL. The 2006 Buffalo Bills season was the franchise’s 47th season as a football team, 37th in the National Football League and first under both general manager Marv Levy and head coach Dick Jauron.  Levy, who previously coached the team from 1986-1997, leading them to four straight AFC Championships and four straight Super Bowl appearances from 1990-1993, replaced Tom Donahoe, who was fired shortly after the end of the 2005 season, with hopes that his 11 full seasons as Bills head coach would improve a franchise that failed to make the playoffs during Donahoe’s tenure.  Jauron, who previously coached the Chicago Bears from 1999-2003, replaced Mike Mularkey, who resigned shortly after Donahoe’s firing, citing family reasons and disagreement over the direction of the organization.  The Bills hoped to improve on their 5-11 record from 2005, while also hoping to make the playoffs for the first time since 1999, but a 30-29 loss to the Tennessee Titans eliminated the team from playoff contention, extending their playoff drought to seven straight seasons, tying a record set from 1967-1973.  For the second consecutive season, the Bills’ opening day starting quarterback was J. P. Losman.
Answer: Mike Mularkey
