New San Francisco 49ers quarterback Brian Hoyer joined KNBR to discuss his decision to sign with the team and reunite with head coach Kyle Shanahan. Hoyer started 13 games in 2014 while Shanahan was the offensive coordinator for a season with the Cleveland Browns. That year, Hoyer passed for a career-high 3,326 yards, completing 55.3 percent of his passes and throwing 12 touchdowns compared to 13 interceptions.

"Obviously, I know that they didn't have any quarterbacks on their roster," Hoyer said. "I knew that I'd come in and have an opportunity to start and I'd come in knowing, a pretty good idea of how to run this offense."

Hoyer went on to say that they now have some players on the roster who are comfortable with Shanahan's offense and it will be up to them to help lead the team. He attributed his leadership skills to watching Tom Brady in New England for three years. "You watch him run a practice and you would think it's a Super Bowl," Hoyer said of Brady. "That's something that I always tried to take with me and kind of emulate was be the guy all the time and not just on Sundays. You've got to earn those guys' respect. It will start day one in April when we start here."

What makes a Shanahan offense so successful? "I think what Kyle does so well is he puts the people he has in the best position to success," Hoyer answered. "We saw that in Atlanta. In Cleveland, what we were able to do with the players that we had was really remarkable. Kyle was a big part of that because he knows how to scheme plays up. He knows how to tie plays together so the defense, when they're looking at the play, everything looks the same except for maybe one thing is different and that's where you have to expose them.

"He's real good at sitting down. He studies a lot of tape. He watches the defense and knows how to attack them and then creates a game plan and makes it so we can go out and be successful and just go out and execute it."
