Oklahoma covering -4 1/2 jumps out at you when you look at the Saturday college football lineup.Am I onto something or just on something thinking this way?So what if the Sooners have a backup quarterback.If Iowa State whooped Nebraska's butt at Lincoln what will a real team do to them?Bo and his brother will be too busy fighting with each other on the sidelines than to worry about the game when they get 20 points behind in the first half.
