There are only two sentences to keep in mind as the 49ers' top offseason story line – the Alex Smith Affair – cranks up over the next four weeks:

• The 49ers want to trade Smith.

• Smith would rather be released and become a free agent.

The rest is fluff designed to influence one of those outcomes.

With that in mind, here are five fibs fans are bound to hear between now and March 12, the start of the league's new year and the first day the 49ers can trade Smith.

1. The 49ers are eager to have both Colin Kaepernick and Smith on the roster in 2013.

That's been the party line for the past month or so. However, the risk of locker room turmoil outweighs the insurance of having two starter-quality quarterbacks on the roster.
