ATLANTA — The Jefferson High football team knocked off the top team in Class AA to earn the program’s first state championship Saturday at the Georgia Dome. The Dragons defeated top-ranked and defending champions Calhoun 31-14 behind three rushing touchdowns and 310 total yards by quarterback Bryant Shirreffs and a dominant performance by the defense, which held the high-powered Yellow Jackets’ offense to its lowest point total of the season. It was the second state championship for legendary Jefferson coach T McFerrin, who led Elbert County to the 1995 state title and later came out of retirement to coach at Jefferson.
