Five storylines: USC vs. Colorado 

October, 18, 2012
1. USC returns home: After playing four of their past five games on the road, the Trojans return Saturday to the Coliseum for an afternoon game in front of a sold-out crowd. The opponent isn’t expected to offer the stiffest challenge, as the Buffaloes are 1-5 on the season and are ranked in the bottom 20 nationally in both total offense and total defense.

2. Trojans into the record books: USC quarterback Matt Barkley is three touchdowns away from setting a Pac-12 career mark for touchdown passes (surpassing Matt Leinart). USC receiver Robert Woods needs 4 catches to establish a USC career receptions mark (moving past Dwayne Jarrett). The Buffs rank last in the conference in pass defense, so the odds are good that the USC players will set those marks in front of the home crowd.

3. Colorado tight end Nick Kasa vs USC linebackers: Kasa measures in at 6-foot-6 and 260 pounds, and that will be a decided size advantage against the smaller and quicker Trojans linebackers. Kasa has caught a touchdown pass in each of the past three games, and he will be one of the primary hopes for the Buffs to score some points.
