Colin Kaepernick and 49ers reached agreement on 6-year extension worth over $100 million tying him to team through 2020, per sources.

That's a pretty substantial contract extension for a guy who struggles to spread the ball around to his receivers, but the 49ers must believe that he can be taught to improve. They must also believe that he is not guilty of sexual assault, a charge he is facing in the Florida court system. Kaepernick has the talent to be one of the top quarterbacks in the NFL, but he is still very much a work in progress. The team has improved its receiving corps over the offseason and the offense should be a force to reckon with so long as Kaepernick continues to work towards improving some of his shortcomings.ANALYST: Howard Bender
