Here”s the grades.

RESULT: NO. 5 OREGON 24, NO. 10 USC 17.

RECORD: 6-2, 3-2.

WEEK 8 GPA: C+.

QUARTERBACK

Mark Sanchez got another conservative game plan and the coaches would argue the interceptions showed what happens when you get too risky. But when you’re in Eugene before the biggest crowd in Oregon history, you need to take risks. Or why play?

C+

RUNNING BACKS

It’s almost ridiculous that USC continues along in its current tailback rotation. But nine defensive coordinators throughout the Pac-10 thank the Trojans.

D+

WIDE RECEIVERS

Patrick Turner finally made some catches that might make people forget DeSean Jackson also wears No. 1. And Vidal Hazleton’s also emerged the past two weeks. It’s inexcusable tight end Fred Davis was not used more (one reception).

B+

OFFENSIVE LINE

Injuries were used as an excuse for several games but the line played intact against Oregon until Sam Baker got hurt. Sanchez spent a lot of the game running for his life.

C-

DEFENSIVE LINE

Pete Carroll complained nose guard Sedrick Ellis got held four or five times in the game. He’s probably more upset Oregon quarterback Dennis Dixon rushed for 76 yards.

B

LINEBACKERS

Brian Cushing’s face mask penalty turned out to be crucial on the Ducks’ game-winning TD drive and they had plenty of problems with Dixon too.

C+

DEFENSIVE BACKS

Oregon receivers were open all day and once again the Trojans finished with no interceptions.

C

SPECIAL TEAMS

A rare game when special teams did not hurt or help. Oregon did a nice job forcing a fumble against itself on the opening kickoff.

C

COACHING

The playcalling wandered between questionable and atrocious. To use Mark Sanchez’s inexperience to limit the game plan is a joke. Didn’t Stanford beat USC with a quarterback playing his first career start?

D+
