Emotion = good. Uncontrolled emotion = bad. Passion = good. Unharnessed passion = bad. These are the lessons UCLA coach Jim Mora is trying to get across to his team as they prepare to host the USC Trojans Saturday in a game that will determine the Pac-12 South Division championship. The implications in this game are significant. For starters, a spot in the conference title game with a shot at the Rose Bowl on the line. Then there's the rivalry factor, Los Angeles bragging rights for a year, the Victory Bell, recruiting implications etc. etc.
