KNOXVILLE — Tennessee’s inability to hang on to the football assured that Florida would continue its mastery of this annual Southeastern Conference series. Feleipe Franks hit three receivers with touchdown passes and ran for a fourth score Saturday night for Florida, which capitalized on six Vols turnovers in a 47-21 rout. Four of Tennessee’s turnovers led to 24 points for Florida. The Vols also gave up a safety and cost themselves a TD by fumbling a ball out of the end zone for a touchback. “Winning the turnover battle is such a huge deal,” Florida coach Dan Mullen said.
