The San Francisco 49ers made arguably the biggest coordinator splash of the offseason when they hired Robert Saleh to be their defensive coordinator, providing a sense of familiarity to the locker room.

San Francisco 49ers linebacker Fred Warner didn't hide his excitement for the return of defensive coordinator Robert Saleh, but there were things he didn't say that illustrate what Saleh's return means for the 49ers' defense.

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.
