New Detroit Lions coach Dan Campbell received a six-year contract from the team, a source told ESPN's Jeremy Fowler.
The Lions announced Campbell's hiring on Wednesday but did not disclose terms. The team will introduce him with a news conference on Thursday.
"With more than 20 years of experience as both a coach and player in the National Football League, Dan knows the rigors of professional football and what it takes to be successful. He will help promote the culture we want to establish across our organization, while also bringing with him high energy, a respect for the game and an identity with which everyone can align themselves," Lions principal owner Sheila Ford Hamp said in a statement.
Campbell, the New Orleans Saints' assistant head coach/tight ends coach, replaces Matt Patricia, who was fired in November after less than three seasons with the Lions and a 13-29-1 record. The Lions will now try to reset after finishing last in the NFC North the past three seasons.
Campbell is expected to bring fellow Saints assistant coach Aaron Glenn with him as defensive coordinator. Glenn has a few other suitors, but Detroit is the favorite, the source told Fowler.
The 44-year-old Campbell, who has never been a coordinator in the NFL, is viewed as a motivator and someone who can bring a team together, rather than an X's-and-O's guru. The Lions had been searching for people they considered unifiers as they identified qualities they deemed important to building a winner out of a franchise that has one playoff win in the Super Bowl era and claimed its last division title in 1993.
Campbell doesn't have much experience as a head coach -- just 12 games as an interim head coach for the Miami Dolphins -- but the Lions clearly saw enough to pair him with recently hired general manager Brad Holmes. Without experience calling plays on either side of the ball, whom Campbell brings in as coordinators will be paramount to his success.
During Holmes' introductory news conference on Tuesday, the Lions said all three of Holmes, Campbell and vice president of football administration Mike Disner will report to team president Rod Wood, creating a balanced structure. When asked whether Holmes or Campbell would have final say over the 53-man roster, Wood said it would be a collaborative process.
"Dan's passion for this opportunity was evident throughout our interview process," Wood said in a statement. "When we began the search for a head coach, it was imperative that we find the right leader who values our commitment to building a winning culture based on organizational alignment and collaboration. The leadership Dan has exemplified throughout his football career has prepared him for this next step, and we are excited to support him as our new head coach."
The Lions had conducted their searches for Holmes and Campbell simultaneously, often asking candidates whether they had people in mind for the other position they would want to work with. After Holmes was hired last week, Ford Hamp said Holmes spoke with some of their remaining candidates.
Campbell played 10 seasons in the NFL, including the final three years of his career for the Lions.
