Miami isn't the only team Alex Smith is visiting. According to a source familiar with Smith's itinerary, the free-agent quarterback also will visit the Seattle Seahawks this week. There is a growing belief that Smith may not be back even if Peyton Manning doesn't sign with the 49ers. Smith, according to sources, is upset at the 49ers, perhaps not because the monetary offer they made him - reportedly $24 million over three years - but because of the job security it provides. Smith felt the 49ers made a commitment to him as their future starter that was not reflected in the contract offer. Source: Sacramento Bee
