NFL Network's Adam Schefter has some ideas on who the 49ers will go after once free agency begins.

Schefter: Look for the 49ers to make a major push to sign Baltimore's free agent linebacker Adalius Thomas, Seattle free agent safety Ken Hamlin, as well as New England free-agent linebacker Tully Banta-Cain.

Along the offensive line, the 49ers are expected to make a significant push for Cincinnati's versatile free-agent offensive lineman Eric Steinbach, who can play any position along the line.
