The Georgia Southern Eagles have plenty of confidence heading into the NCAA volleyball tournament, and why shouldn’t they? The Eagles (28-5) won regular season tournaments at Ole Miss, South Alabama and a pair at home in Hanner Fieldhouse, and also won the Southern Conference tournament on Nov. 24, in Greenville, S.C. They face ACC champion and 16th-ranked Florida State (24-7) today at 5 p.m., in Gainesville, Fla., to open their first trip to the NCAA tournament since 2010. “This is a goal that we set early in the season — to get past the first round of the tournament — so now we just have to take care of business,” GSU outside hitter Jamie DeRatt said.
