CONWAY, S.C. — Coastal Carolina had a lot of emotion left over from last weekend’s five-overtime loss to Towson, a senior quarterback who passed for a ton of yards and a defense set on shutting down the run. But Georgia Southern had all the luck. In a game that saw a pair of fluke interceptions, a blocked punt and a two-man return on a blocked extra-point conversion, The Eagles got all the right bounces and held on for a 43-26 win at CCU Saturday night.
