After Davis deal, who's next for 49ers?

The San Francisco 49ers have done a fine job of amassing an impressive collection of young talent on their roster, and they're certainly one of the favorites to contend for the Super Bowl again in 2013. As of now, much of that young talent is being retained at a team-friendly rate (thanks to the new CBA), but that situation will need to be rectified in the coming seasons as those deals expire.
