Ian Book and the Notre Dame offense struggled mightily for 40 minutes before scoring two touchdowns to catch and pass the upset-minded Pittsburgh Panthers by 19-14 on Saturday. After finally taking their first lead with 5:43 left in the contest, the Irish had to rely on another great defensive stand led by Khalid Kareem and Julian Okwara to put the game on ice and move to 7-0 on the season. Book hit Miles Boykin with his best throw of the day, a 35-yard strike on a deep post, for the winning points.
