Whenever I talk to Pitt fans about their reasons for attending (or not) games, two things generally stand out in addition to the time: the quality of the opponent and the quality of the Pitt team. In other words, fans don't want to show up to Heinz Field to see a mediocre Pitt team take on a weak opponent.
Recently, ACCFootballRx decided to rank all of the home schedules of ACC football teams this year. The Panthers finished squarely in the middle with four of their games coming against quality opponents (Oklahoma State, North Carolina State, North Carolina, and Miami).
