Crennel played baseball and football at Fort Knox (Ky.) High School and Amherst County (Va.) High School before committing to college football at Western Kentucky. Although he was a four-year starter as a defensive lineman, he became an offensive lineman during his senior season at the request of the coaching staff. He was named the team's MVP after the switch but was not drafted and never played in the NFL. While the move did hinder his draft chances, it increased his knowledge of the game, by experiencing the trenches from both the offensive and defensive side of the football. Crennel earned a bachelor's degree in physical education from Western Kentucky University, and then a master's degree while serving as a graduate assistant for the school in 1970.
College coaching careerEdit
Western Kentucky UniversityEdit
After one season as a graduate assistant with Western Kentucky (1970), Crennel served as the defensive line coach for three seasons (1971–1974).
Ole Miss and Georgia TechEdit
National Football League coaching careerEdit
New York GiantsEdit
After spending two seasons as an assistant with the New York Giants, Crennel became the special teams coach for seven seasons (1983–1989) and the defensive line coach for three seasons (1990–1992). In 1983, he was reunited with Parcells as the head coach.
New England Patriots and New York JetsEdit
Crennel left the Giants after the 1992 season and worked as the defensive line coach for the New England Patriots for four seasons (1993–1996) and for the New York Jets for three seasons (1997–1999) during the time that Parcells was the head coach in each franchise.
Crennel was hired as the Cleveland Browns' defensive coordinator for the 2000 season.
Return to New EnglandEdit
After one season in Cleveland, he filled the same role with the Patriots for four seasons (2001–2004) under long-time friend Bill Belichick. The two had worked together on the Giants from 1981 to 1990 and had served on Parcells's staffs in New England and the Jets from 1996 to 1999. Crennel helped lead New England to three Super Bowl victories (2001, 2003, & 2004).
Kansas City ChiefsEdit
On January 13, 2010, Crennel was hired as the Kansas City Chiefs defensive coordinator, reuniting him with offensive coordinator Charlie Weis and General Manager Scott Pioli from their days with the Patriots.
On January 20, 2014, Crennel signed a 3-year deal with the NFL's Houston Texans becoming their new defensive coordinator under their new head coach Bill O'Brien. He was one of the highest paid defensive coordinators in the NFL for three seasons (2014-2016), earning roughly $1.8 million per year. Crennel finished the 2016 year with the NFL's #1 ranked defense and in January 2017 was promoted to Assistant Head Coach. On January 20, 2018, he returned to his role as defensive coordinator for the Texans after Mike Vrabel left to become head coach of the Tennessee Titans.
Before beginning the 2003 playoffs with the Patriots, Crennel interviewed for head coaching positions with six teams in under 36 hours. He was not offered any jobs, however, and was passed up by the New York Giants, the Buffalo Bills, the Arizona Cardinals, the Chicago Bears, and the Atlanta Falcons.
Crennel was hired to replace Butch Davis as head coach of the Cleveland Browns. He went 24–40 in his tenure with the Browns. His team went 6–10 and 4–12 in his first two seasons with the Browns, finishing last or tied for last in the AFC North and missing the playoffs each year. The Browns finished the 2007 season with a 10–6 record, just falling short of making the playoffs–only the franchise's second winning season since its revival in 1999. Crennel's success in the 2007 season earned him a two-year contract extension in January 2008.
On December 29, 2008, following a disappointing 4–12 season, Crennel was fired by the Browns.
Kansas City ChiefsEdit
Crennel joined the Kansas City Chiefs as defensive coordinator in 2010. Following Todd Haley's termination as the team's head coach after 13 games in the 2011 season, Crennel was named the team's interim head coach for the remaining three games of the season. Crennel won his first game as the interim head coach of the Chiefs on December 18, 2011 against the then undefeated Green Bay Packers 19–14, which was significant as Crennel snapped the Packers' 19-game winning streak and ended their hopes for a perfect season. Crennel finished his stint as interim head coach with a 2–1 record. However, in his tenure as a head coach for the Chiefs, Crennel would only win 2 more games finishing with a 4–15 overall record.
On January 9, 2012 Crennel was named the 11th full-time head coach in Chiefs history. Three days later, Crennel announced his intent to remain as defensive coordinator during his tenure as head coach.
On December 1, 2012, Crennel attempted to prevent the suicide of player Jovan Belcher by talking to him and witnessed his death by a self-inflicted gunshot wound to the head. The following day, Crennel coached his team to a 27–21 victory over the Carolina Panthers, the Chiefs' first home victory since defeating the Packers the previous season, and the only other home win during his tenure.
On December 31, 2012, it was announced that Crennel had been fired from the Chiefs.
