COSTA MESA, Calif. -- Even though he served as interim head coach and was considered one of the front-runners for the job, Anthony Lynn never thought he'd be the head coach of the Buffalo Bills.
A protégé of Rex Ryan, who worked under the charismatic head coach with the New York Jets and Bills, Lynn said he was considered part of that culture even though he had a different temperament and personality as a coach.
And the Bills' front office appeared to want to move away from the Ryan regime, hiring former Carolina Panthers defensive coordinator Sean McDermott as the team's head coach in January.
The move has worked out so far in Buffalo, with the Bills (5-4) in the AFC playoff hunt heading into Sunday's matchup against the host Los Angeles Chargers (4:05 p.m. ET, Fox).
Lynn landed on his feet as well, securing a head-coaching job with the Chargers (3-6).
"I'm where I want to be," Lynn said. "I interviewed there and they went a different direction. I didn't think I was the favorite there anyway because how many times do you hire a guy from the staff when you fire the head coach? It doesn't happen too often. I did appreciate the interview, but I'm where I want to be."
Along with filling in as the team's interim head coach last season when Ryan was let go one game before the completion of the 2016 season, Lynn also served as the team's offensive coordinator in 2016, and before that was the running backs coach for two seasons.
Other Chargers with ties to the Bills heading into Sunday's home contest include offensive line coach Pat Meyer and defensive line coach Giff Smith, who served in the same roles for the Bills.
Lynn's son D'Anton Lynn, a defensive assistant for the Chargers, also worked as a defensive assistant for the Bills when his father was on the staff. Quarterback Cardale Jones and offensive tackle Michael Ola played for the Bills.
Chargers general manager Tom Telesco grew up in Buffalo and worked as an intern for the Bills during summers for four seasons.
Lynn said his experience and familiarity with the Bills should aid him in devising a game plan for Buffalo this week.
"It definitely helps, understanding that personnel and the psyche of some of those players," Lynn said. "All of that definitely helps, so when we start game planning, I'm sure there will be some tweaks based on just their personnel alone."
A focus for Lynn this week will be jump-starting an offense that is averaging 18.6 points per game, which ranks No. 23 in the NFL.
Quarterback Philip Rivers is in the NFL's concussion protocol this week, so Lynn and offensive coordinator Ken Whisenhunt will have to put together a game plan with backup Kellen Clemens in mind in case Rivers is not cleared by Sunday.
Lynn said he has no intention of taking over playcalling duties or making any other staff changes on offense.
"I left this staff here together for a reason," Lynn said. "I wanted continuity for this offense, because I felt good about what they've done in the past.
"I just wanted to eliminate some of the turnovers and increase the rushing reps just for balance. But I have complete confidence in our offensive staff. And I'm sure we'll get this figured out."
