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.

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.
