UCLA had 3 fumbles, 2 of which they lost and also a pass interception, so they didn't exactly play a perfect game. 3 turnovers. They had almost 500 yards offense, basically 300 yards rushing and 200 yards passing. Again, they did whatever they wanted. Did Harmon's fumbles play a huge part in that game? Clearly. You also can't argue that giving up 500 yards and 45 points makes it pretty hard to win a game.
