ATLANTA — Duke coach David Cutcliffe points to the Blue Devils’ two straight wins over Georgia Tech as evidence the program is on the rise. A third straight win in the series on Saturday would be particularly reassuring to Duke fans, since the Blue Devils have lost their first three Atlantic Coast Conference games this season and are last in the Coastal Division — just ahead of the Yellow Jackets. Duke (3-4, 0-3 ACC) should enter the game with good background in the triple-option plays in Georgia Tech’s spread-option offense.
