Barnes battled for the Bulldogs' starting job in the fall but ended up fourth on the depth chart and will be projected third if he returns next season.
"It's been a tough year, just not having the opportunity to play is always tough, but I've definitely still learned a lot and improved and gotten better so it's been good at the same time," he said.
Barnes is a Mississippi native but his parents moved to Atlanta last year when his father took a job with the Federal Reserve. "With all of that, it would be a very tough decision to (leave)," he said. "I feel at home here."
