2nd quarter of Rose Bowl

The key has been the passing game.  The Penn State corners can not cover the USC wide receivers or their defensive scheme is just inadequate.  

Either way this aerial attack looks like it is just dominant.  And of course that is opening up the running game and running attack.  

Also USC's defense had some crucial third down stops and third and short but they were all running attacks.  One was off tackle and one was up the middle.  Both were stopped.
