"Every season is different," Harbaugh said. "I don't really believe in the defending champ thing. It's not boxing. They don't give you a belt and you fight for the title. We were the champions of 2012. The NFL champions were the Baltimore Ravens. Who is next year's champion depends on who plays the best, who handles adversity the best and who comes out on top. Our guys are just the men for the job. Can't wait to get started."
