The San Francisco 49ers welcomed back a familiar face, re-hiring Robert Saleh as their defensive coordinator. However, one former player who once thrived under Saleh’s leadership will have to watch from across the country as the reunion unfolds.

Saleh, who was fired in October as the New York Jets head coach five games into his fourth season, generated interest on the head-coaching front and was seen as one of the frontrunners for the Jacksonville Jaguars job. He also interviewed with the Las Vegas Raiders and Dallas Cowboys.

Robert Saleh cannot personally create turnovers, rush the passer or stop the run. His return as the 49ers’ D-coordinator is no guarantee of success.

The San Francisco 49ers have long established their strong defensive identity, and with Robert Saleh back at the helm

Later on Thursday, then-Tampa Bay Buccaneers offensive coordinator Liam Coen had a change of heart, the Jacksonville Jaguars quickly moved to hire him as head coach and Saleh, who told Kyle Shanahan and John Lynch that he’d return to the 49ers if he didn’t get a head-coaching job, stayed true to his promise.

Saleh was fired as the Jets’ coach five games into this season and is now back with the 49ers, where he made his name in the NFL.

The San Francisco 49ers are bringing back Robert Saleh for a second stint as defensive coordinator after a failed tenure as head coach of the New York Jets.

The biggest concern surrounding the San Francisco 49ers' reunion with Robert Saleh is the possibility of him becoming the team's third consecutive one-and-done defensive coordinator.
