The opening line for this game is only -3.5. What does Vegas know that us fans do not? They aren't in the business of giving away money.

I know PSU still has a talented roster, but a backup QB and an interim coach do not scream close game. They expect a gritty, throw everything at OSU and keep it close? Knowles to have the game of his life? What am I missing and why do I not bet the house on this spread?
