Easy, whenever (if-ever) ISU is leading, turn off the play clock (due to a "malfunction") and for every down just blow the whistle RIGHT after ISU snaps it and call a delay of game.
Keep doing this until they're backed up to their goal line and then when ISU has the ball in their own endzone blow the play dead due to the QB or RB's forward progress being stopped and its 2 points and the ball for KSU.
