KENNESAW — It’s been the story of Gainesville’s season, and especially so in the playoffs: razor-thin margins for error, a different hero seemingly every night, and most importantly, an awful lot of wins. Even with the heightened stakes and in an unfamiliar environment, the Red Elephants showed they’re comfortable with that script, taking a thrilling 63-62 win over Effingham County on Saturday night in the Class AAAAA state semifinals. Gainesville (23-9) will meet Miller Grove in the state championship game at 8:45 p.m. Friday in Macon, and they’ve got senior Tray Harrison to thank for the trip.
