Its a game of wholes and halves-Its a game of 3's and 7's.You should always consider the NFL as a game of 3's(Thats what I was taught many years ago)
The college side can be both so take the number that favors your pick-Furmanski is absolutely on when he says its hard to hedge a one pointer-Just my opinion with this game-IF you like OU take the 6.5.
Either way-Good Luck Bro
