The Falcons, who are trying to improve their power and short-yardage-offense package, are interested in Dallas Cowboys fullback Keith Smith, according to a person familiar with the situation. Smith is a restricted free agent to whom the Cowboys do not plan to make a tender offer. He’ll become an unrestricted free agent March 14. Smith, who’s 6-foot-2 and 232 pounds, is a converted linebacker. He played at San Jose State. Smith has played in 32 games the past two seasons with four starts. He’s mostly been a lead-blocker for running back Ezekiel Elliott and has only two carries and has caught eight of nine passes for 46 yards. The Falcons are considering a better lead-blocking fullback. They are also taking a long look at both guard positions, which were manned by Andy Levitre and Wes Schweitzer last season.
