SANTA CLARA, Calif. -- The San Francisco 49ers and the agent of Colin Kaepernick will surely talk about a contract extension in the offseason.Let's look at the situation:Why he's up for a deal: Kaepernick was a second-round pick in 2011. His contracts runs through 2014. He is set to be an unrestricted free agent in March, 2015.What should he expect: It's an interesting situation. After Kaepernick led the 49ers to the Super Bowl in less than a full season as a starter, it would expected that Kaepernick would cash in as soon as he could -- after this season.
