The No. 15 Bluejays had questions coming into the season. Pop Isaacs answered some of them with his 24-point performance in Saturday's exhibition against the No. 14 Boilermakers.
Darius Perrantes was 25-of-34 passing for 412 yards and five touchdowns and John Erby had eight receptions for 138 yards and two TDs to help Duquesne beat Stonehill 48-34.
