GREENSBORO, N.C. — For a team that’s famously reliant on its ground game, Georgia Tech sure has developed a few players capable of catching the ball. Now coach Paul Johnson is looking for the next big-play receiver to follow NFL wideouts Demaryius Thomas and Stephen Hill. Thomas had 2,339 yards receiving — fourth in school history — during his three-year career while Hill led the nation with an average of 29 yards per catch.
