"Kyle played receiver, and so he knows how to get receivers the ball. That's definitely what made it work for me in this offense. I'm just happy that he's running the show."

This is only the third time Garçon has had a change of scenery over his nine-year career. He spent his first four seasons with the Indianapolis Colts before spending the last five in Washington.

The West Palm Beach, Fla., native is eager to begin a new chapter in the Bay Area.

"I'm just very excited," Garçon said. "It's a new part of the country, which gives you new energy. I've never lived out on the West Coast. I've got a lot of friends out here, and so I'm looking forward to it. New beginnings always give you new energy to prepare, to be happy, to show your worth and to show your value."

Garçon was introduced to 49ers fans at a press conference featuring six other free-agent additions, all of whom are building blocks of Shanahan's vision for the team.
