Purdue needs to follow the formula of South Florida and Michigan to score a win over intra-state rival Notre Dame at Ross-Ade Stadium.
Like the Bulls and Wolverines, the Boilermakers (2-1) need to capitalize on mistakes by the Irish (2-1). Notre Dame had 10 turnovers in the two losses that started the season.
Notre Dame has made plenty of mistakes this year on offense, turning the ball over 15 times. Quarterback Tommy Rees has been the main culprit with nine turnovers (six interceptions, three fumbles).
If Purdue can improve on its one turnover per game average, the Boilermakers could pull off the upset tonight.
But if Rees' turnover problems seem to start to affect the game, don't be surprised if the Irish lean on the running game.
Cierre Wood and Jonas Gray have revived Notre Dame's ground game this season, and the Irish enter tonight averaging 152.8 yards per game.
As long as Notre Dame limits mistakes, this should be an Irish win, 28-14.
