JEFFERSON — After a season filled with convincing victories, the Dragons will be a decided underdog heading into the Class AA state championship game at 2:30 p.m. Saturday at the Georgia Dome in Atlanta. Calhoun (14-0) is the defending Class AA state champion and has been in the state championship game every year since 2008, while Jefferson (13-1) hasn’t been this far since 1977. The Dragons aren’t, however, completely lacking in experience.
