FILE - In this Dec. 19, 2011 file photo, San Francisco 49ers head coach Jim Harbaugh, center, talks with quarterback Alex Smith (11) during the second quarter of an NFL football game against the Pittsburgh Steelers in San Francisco. In the Bay Area, they're beginning to think about the possibility of Jim Harbaugh coaching former Indianapolis Colts quarterback Peyton Manning and believe it truly might happen. 49ers free agent quarterback Alex Smith traveled to Miami Sunday, March 18, 2012, to meet with the Dolphins. But if San Francisco doesn't sign Manning the 49ers will have some serious relationship-building to do with Smith. (AP Photo/Paul Sakuma, File) Photo: Paul Sakuma, Associated Press
