The 49ers have 39 of their own draft choices on their roster, five more than the league average, with 34 entering the NFL under Mike Nolan (20) or Mike Singletary (14).
This is largely a home-grown team.
The chart lists 49ers draft choices still with the team, broken down by drafted round.
Andy Lee, Shawntae Spencer and Isaac Sopoaga remain from the Dennis Erickson draft classes. Eric Heitmann and Brian Jennings remain from the Steve Mariucci classes (another player, cornerback Keith Smith, was drafted by the Lions when Mariucci was their head coach.
Why haven't the 49ers been more active in free agency? One reason: They like their current draft choices more than they did a few years ago, so they see less need to cover for draft mistakes.
