The Browns have added another punter, signing free agent Jake Schum. Like Schum, he hasn’t kicked in an NFL regular-season game. The signing of Schum gives the Browns two punters under contract. Schum, 24, posted a 39.0-yard average in 2011 as a senior at the University of Buffalo. According to the Spectrum, the university’s independent student paper, Schum worked out at Buffalo’s pro day earlier in March. Spencer Lanning, the other punter on the roster, has kicked in six preseason games in the last two summers. Reggie Hodges, who punted for the Browns last season, is an unrestricted free agent.
