Colorado: By the numbers

0: The number of times that Colorado has defeated USC in the six times that the two programs have met

The Buffaloes have lost all six matchups with the Trojans dating back to a 46-7 loss in 1927. USC defeated Colorado last season in Boulder 42-17 thanks in part to six touchdown passes by Matt Barkley.

4.5: The number of sacks that the Colorado offensive line allows per game, the highest average in the nation

Marked by inconsistent play along the offensive line, Colorado has given up 27 sacks in just 6 games in 2012. Arizona State racked up 5 sacks alone against the Buffaloes last week.

41.3: The average points per game that Colorado is allowing this season

The Colorado defense has struggled mightily, and the Buffaloes currently rank No. 117 nationally in points allowed per game. They also allow 494.2 total yards per game -- the No. 113 mark.

42: The number of plays from scrimmage that the Colorado defense has given up in 2012 that have been 20 yards or greater

Only Ball State has given up more big plays of 20 yards or more than the Buffaloes. Of those 42 plays, 31 have come through the air against a suspect Colorado secondary. In contrast, USC has given up just 14 plays from scrimmage that have been 20 yards or greater.

88.2: Colorado’s red zone scoring percentage

Surprisingly, Colorado’s offense is one of the country’s most successful once they reach their opponents’ 20-yard line. Having scored on 15 of 17 opportunities in 2012, they currently rank No. 2 in the Pac-12 and No. 27 nationally in this category.
