As a college football fan, as well as a Northwestern fan who saw them early in the season, let me tell you that they could very easily have two by now. Penn State could also very easily have zero losses by now, as they lost one very close game and won one. Similarly, Northwestern could very easily have another loss if they hadn't gotten lucky on the onside kick versus Iowa. Hell, USC could've easily had a loss if Leinart hadn't fumbled the ball out of bounds against ND. That's the way college games work, you get an L or a W, and hopefully the close games even out in the end. Northwestern also beat NIU by just 1 point.
