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.

Robert Saleh is back as defensive coordinator of the 49ers, and all is right with the world. For now, anyway. Coach Kyle Shanahan has cycled through DeMeco Ryans, Steve Wilks and Nick Sorensen after Saleh’s departure following the 2020 season to become head coach of the New York Jets.

Robert Saleh, who ran the Niners' defense from 2017 to 2020, is heading back to San Francisco for the same role after a three-plus-year stint as Jets coach.

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, a person familiar with the choice told The Associated Press.

Robert Saleh, who was fired by the Jets during the season, was hired by the 49ers for second stint as the team’s defensive coordinator on Friday night.

Saleh was fired midway through this past season in New York, but the Jets had a strong defense under his tenure.

Following his dismissal as head coach of the New York Jets, Robert Saleh has wasted no time finding his next opportunity in the NFL. The former Jets leader has returned to the San Francisco 49ers, where he previously thrived as defensive coordinator.

The 49ers are going all-in for a Robert Saleh reunion. The former New York Jets head coach has an offer on the table from San Francisco to become the highest-paid defensive coordinator in the NFL, according to The Athletic’s Matt Barrows.

A former New York Jets coordinator who spent almost a decade with the franchise is moving on to the San Francisco 49ers.

Now that the San Francisco 49ers have hired Robert Saleh, some believe he'll bring a key defensive player from the New York Jets with him.
