Veteran wide receiver Emmanuel Sanders is the 49ers' top offensive free agent.
Sanders should be one of the top receivers on the NFL free-agent market, which unofficially begins Monday with the two-day opening negotiating period before the new league year starts on Wednesday.
Dallas’ Amari Cooper is the top receiver scheduled for free agency. Cincinnati’s A.J. Green, who missed all of last season with an ankle injury, and Robby Anderson of the New York Jets should also receive a lot of attention, if they make it to free agency.
The 49ers might deem Sanders too expensive to re-sign.
