Armando Allen Jr., RB: Purdue coach Danny Hope called Allen the difference. He had 18 carries for 93 yards and a touchdown.
Gary Gray, CB: Gray tied for the team lead in tackles with nine and helped cause an interception by batting a pass away near the goal line.
David Ruffer, K: Ruffer won the kicking competition late in the week before the game and rewarded the coaches' decision by making all three of his field goal attempts.
