The San Francisco 49ers will have 20 free agents in a couple of months. Seventeen of those free agents are unrestricted, while three are classified as restricted free agents.
A couple of things to know before free agency takes place:
-- Unrestricted free agents can negotiate exclusively with the San Francisco until the new league year begins on March 9.
-- Restricted free agents could be tendered a contract. If so, the 49ers would have the right of first refusal to match any offers they may receive.
-- Teams have until 1 p.m. PT on March 1 to designate franchise or transition tags for their free agents.
