NEW YORK — Three days after being scolded with a seat on the bench to start a game, Pitt’s senior leaders responded by playing with the type of urgency coach Kevin Stallings was hoping to see. With their renewed effort, the Panthers might have pushed Georgia Tech off the NCAA bubble. Michael Young scored 17 points and Jamel Artis added 11 points and nine rebounds as Pittsburgh rode its top two players to a 61-59 victory against Georgia Tech on Tuesday night in the first round on the Atlantic Coast Conference Tournament.
