ATLANTA — The Pittsburgh Panthers are looking rejuvenated under first-year coach Pat Narduzzi with a chance to stay unbeaten in the ACC. Georgia Tech’s season is headed in the opposite direction. Considered the early favorite to win the league’s Coastal Division, the Yellow Jackets are riding a four-game losing streak, their worst in eight seasons under coach Paul Johnson. Getting quarterback Justin Thomas back in a groove is critical for Georgia Tech (2-4, 0-3 Atlantic Coast Conference).
