PHILADELPHIA — The Sports Network announced its 2013 preseason All-America teams Monday, with two Georgia Southern juniors — running back Dominique Swope and offensive tackle Garrett Frye — representing the Eagles on its first and second teams, respectively. Swope became the Eagles’ first back-to-back 1,000-yard rusher since Jermaine Austin in 2002-2003, and finished the 2012 season with 1,246 yards and 16 touchdowns. Frye was selected a third team All-American by the Associated Press and The Sports Network last season, helping Georgia Southern to its ninth NCAA rushing title in 2012 with a 399.4 yards per game average.
