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.

That’s not a huge surprise given the tumult San Francisco has dealt with the last couple of years while cycling through defensive coordinator Steve Wilks and Nick Sorensen.

Saleh has a proven track record with Warner and the 49ers, and his addition to their coaching staff looks like an early offseason victory for San Francisco. Warner expressed his excitement in an interview with NBC Sports’ Jennifer Lee Chan at the Pro Bowl Games.

“It means a lot,” Warner said. “Obviously Coach Saleh has been amazing for us and for myself as a young player, so it’s gonna be interesting being the old guy now, myself, being with him again. It’s gonna be fun though.”

A clearer indication of what Saleh brings to the 49ers defense came from something Warner did not say.

Chan asked the All-Pro LB about Saleh’s energy and how it lifts up the 49ers defense. His response was telling:

“I mean, it’s contagious,” Warner said. “You see it. Him, DeMeco (Ryans), that was a big part of why we were so successful. And obviously the teaching portion of it all and making sure we’re all on the same page. It’s gonna be good to get him back.”

Saleh and Ryans were both high-energy coaches on the sidelines. That was not a quality possessed by Wilks nor Sorensen, and Warner omitting them both is telling.

Overt displays of excitement on the sideline aren’t the only requisite quality for a good defensive coordinator, but it’s been clear the last couple of years the 49ers edge has been lacking on that side of the ball. There have been other problems, too. Warner alludes to them when talking about teaching and being on the same page. Personnel has also been an issue that goes beyond the scope of a DC’s responsibilities.

Warner’s excitement and his reasons for it are good signs for the immediate future of the 49ers’ defense. They’ve got a handful of other tweaks to make, but just getting Saleh back on the sideline should help San Francisco right away.
