Niners in CB market?

Following the trade agreement in principle sending Alex Smith to the Kansas City Chiefs, the San Francisco 49ers will be armed with 12 draft picks this offseason, and that's before the compensatory ones are awarded (some have estimated the Niners will get another three). So they'll be able to use the draft to find themselves some new key players to continue building towards a championship roster. But that doesn't mean they're going to resist doing some shopping in free agency.
