By the numbers: '12 season review edition

0: The number of ranked opponents that USC has defeated this season.

The Trojans were 0-4 against top-25 opponents in 2012 -- all seven of the Trojans’ victories have come against unranked teams.

1: Where Marqise Lee's 112 catches and 1,680 receiving yards rank him in the Pac-12 single-season record books

Lee also ranks No. 2 nationally this season in receptions (9.3 per game) and receiving yards (140 per game), and No. 3 in all-purpose yards (215.7 per game).

3: The number of games that USC lost in November

Garnering a reputation as a dominating team in the month of November in recent years, the Trojans compiled a record of 1-3 in that same month in 2012. During the Pete Carroll era from 2001-2009 the Trojans lost just one contest in November.

4: USC’s ranking nationally in sacks with 3.58 per game

If there is one area where the Trojans have exceeded expectations, it’s in the team’s pass rush. After compiling just 31 sacks in 2011, the Trojans have racked up 43, including 36 by the surprise unit of the squad, the defensive line.

5: The number of games that USC has lost this season, the most by a preseason A.P. No. 1 ranked team since Ole Miss went 5-5-1 in 1964

If the Trojans finish the season unranked, they would also become the first preseason A.P. No. 1 ranked team to do that since, again, the 1964 Ole Miss squad.

17: The number of years since USC lost to both UCLA and Notre Dame in the same season

The Trojans last went 0-2 against their rivals in 1995, when John Robinson was the head coach.

31: The number of times that USC turned the ball over in 2012 -- the No. 111 mark nationally

This comes one year after USC turned the ball over just 18 times -- the No. 20 mark nationally. Seventeen of the 2012 turnovers have come in the form of interceptions, including a career-worst 15 by Matt Barkley.

35.8: USC’s third-down conversion percentage this season -- the No. 93 mark nationally

A crucial aspect of the Trojans’ struggles, the offense successfully converted just 49 of 137 third-down attempts.

48: The number of points that USC was outscored by in the first quarter of the team’s five losses

Outscored 58-10 in the opening quarter in the five games that it has lost, to say that USC has had a knack for starting out slow would be an understatement. The lowest point of all came against UCLA, when the Trojans fell behind 17-0 after one quarter of play, and 24-0 midway through the second quarter.

451.9: The number of total yards per game that the USC offense has averaged in 2012 -- the No. 30 mark nationally and the sixth most in school history

Although inconsistent, the USC offense put up stellar numbers at times, thanks in large-part to a Barkley-led passing game that racked up 296.9 yards per contest.
