NASHVILLE, Tenn. — Florida coach Billy Donovan knows his newly top-ranked Gators are an even bigger target for opponents. They just keep finding ways to finish off victories.Dorian Finney-Smith scored 19 points, and Florida, playing its first game at No. 1, held off Vanderbilt 57-54 on Tuesday night to clinch at least a share of its second straight Southeastern Conference title and seventh overall.The Gators are 13-2 in games decided by single digits after losing all six last season, and Donovan said their margin for error is not very big.“We’re not an overly talented team, we’re just not,” Donovan said.
