Kyle Shanahan's coaching style occasionally leaves his players speechless.
The 49ers coach explained to reporters Wednesday his strategy of deciding to call out a specific player or not during film sessions.
"I think most of it just happens," Shanahan said. "I think maybe how you do it can sometimes be to get a reaction from people but it's very simple with me because it all just goes off of what I see on tape and I'm pretty consistent with that."
Shanahan adds that when he asks a player to break down film of the entire team, he often gets a nervous silence as a response.
"It's crazy ... you got a lot of grown men, they hear their name in a big room, they get real nervous, which is crazy," Shanahan shared, much to the delight of the reporters in the room. "Ask them to break down [their own plays], they talk nonstop and then you ask them to break down the team one day and it's just like crickets.
"So I think it's good practice for everybody, [to] be in those situations."

Shanahan isn't a stranger to calling out a certain player to get the most out of them. Before the 49ers' 33-17 win over the Miami Dolphins on Dec. 4, Shanahan had some choice words for Nick Bosa, leading to a dominant outing at Levi's Stadium.
