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 didn’t get the job he wanted, but the job he accepted could lead to a gig he desires next year. Saleh rejoined the San Francisco 49ers as their defensive coordinator Friday and the announcement was made shortly after the last of the three head-coaching openings for which he was a candidate was filled.

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.

Robert Saleh is expected to return to the 49ers as their defensive coordinator if he doesn't become a head coach according to The Athletic and NBC Sports Bay Area.

Could the San Francisco 49ers bolster their defense around new coordinator Robert Saleh thanks to his New York Jets ties?

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.
