On Wednesday, the 49ers hosted USA Football/Max Preps High School Football Media Day at Levi's Stadium.
Jim Tomsula wasn't scheduled to speak, but he took the podium and shared insight on several topics.
After telling the players in attendance to listen to their coaches, the 49ers' first-year head coach warned the high schoolers about the dangers of social media.
“Gosh, be careful. Be careful," Tomsula stressed. "I’m learning a lot about it. I don’t know a lot about it, other than my children, my daughters, are teaching me something about it and I’m a paranoid mess with it.
