ATLANTA — With Georgia Tech cruising toward an apparent rout, many of the gold-clad fans didn't bother hanging around for the second half. Boy, what a comeback — and finish — they missed. Georgia Southern scored 28 straight points after halftime to stunningly grab the lead, but the Yellow Jackets came up with a huge defensive play and pulled out a 42-38 victory when Justin Thomas threw a 13-yard touchdown pass to Deon Hill with 23 seconds remaining Saturday.
