Most significant signing: Receiver Anquan Boldin. Fans may not like it when a team's most significant move is keeping one of its current players, but imagine if Boldin had walked. In his first season with the 49ers, Boldin became a critical part of the offense. Receiver was one of the team's biggest need areas. Re-signing Boldin helps keep this offense dangerous. The team's plan was to try to keep its best players, and Boldin was the top priority.
