Saleh’s hiring was announced Friday night after three others — DeMeco Ryans, Steve Wilks, Nick Sorensen — succeeded him as Shanahan’s initial defensive coordinator from 2017-20.

“I do think it’s an avenue we can get better in,” Shanahan said Jan. 8 about the 49ers’ special teams. “And you can’t change the whole thing out so Brian ends up being the fall guy for that and I really appreciate him. He did have a real good three years here and worked his tail off and was very loyal to us and is a very good coach …  Special teams is a part of football and everything a part of football is extremely important to us.”

The 49ers have yet to announce the completion of their offensive coordinator search, which was required under NFL protocol despite Shanahan’s premature promotion of Klay Kubiak to that role three days after their season ended.
