AUBURN, Ala. — Isaiah McKenzie, Aaron Davis and Georgia’s defense took the game — and the ball — into their own hands. McKenzie returned a fourth-quarter punt 53 yards for a touchdown Saturday to lift the Bulldogs to a 20-13 win over Auburn in a battle of the Southeastern Conference’s preseason division favorites. “He (Kevin Phillips) outkicked his coverage and like Coach told me all week, ‘If you get a pitch to hit, take it,’” McKenzie said.
