The Detroit Lions' coaching staff could take another hit as the coach of their best unit has gotten a second interview with the Seattle Seahawks.

The Detroit Lions have lost some key coaches this offseason. Ben Johnson took the head coach job with the Chicago Bears, Aaron Glenn took the head coach job with the New York Jets and Terrell Williams took the defensive coordinator job with the New England Patriots.

The 50-year-old Williams coached defensive line for Mike Vrabel for six seasons in Tennessee, also serving as the team’s assistant head coach for Vrabel’s final season.

According to reports, the New England Patriots want to hire Detroit Lions defensive line coach Terrell Williams as their next defensive coordinator.

Terrell Williams spent six seasons working with new Patriots coach Mike Vrabel before coming to Detroit last winter.

New England Patriots head coach Mike Vrabel has made his second big hire, snagging another former Detroit Lions coach for his defensive coordinator.

It’s been a long time coming, but Ben Johnson (Chicago Bears) and Aaron Glenn (New York Jets) are off to run their own franchises. Who they take with them is the next question, but what we do know right now is that Dan Campbell is tasked with replacing two of his closest confidants in the middle of a Super Bowl window.

A comprehensive list of reports on which coaches are interviewing with the Detroit Lions for offensive coordinator, other staff movements.

Detroit’s staff changes started on Monday when Ben Johnson became the new head coach of the Chicago Bears. They continued when Aaron Glenn became the head coach of the New York Jets, and Terrell Williams left to become the defensive coordinator for the New England Patriots Wednesday.

According to NFL Network's Tom Pelissero, the Lions are promoting offensive line coach Hank Fraley to run game coordinator/offensive line coach. The move should keep Fraley with the Lions amid concerns he could leave to become an offensive coordinator elsewhere.

Offensive line coach Hank Fraley, considered a potential offensive coordinator the Chicago Bears, is set to stay put with the Detroit Lions.
