A look back on the week that was.

Team of the week: Stanford rolled up 510 yards of offense against one of the nation's best defenses in a 42-17 win against Arizona. The Cardinal defense wasn't too shabby either while holding the Wildcats to 15.6 points less than their season scoring average. A Facebook page has been set up to promote the Cardinal's potential availability for an at-large BCS bowl berth.

Best game: USC's entertaining 34-33 win against Arizona State included: 1. Two long interception returns for TDs; 2. A 100-yard kickoff return for a score; 3. A blocked PAT returned for a critical 2-points for USC; 4. 46 second-half points after a rather slow first half; 5. A missed potential game-winning field goal by slumping Arizona State kicker Thomas Weber, a former Groza Award winner; and, 6. A personal foul penalty from linebacker Vontaze Burfict (again) that helped set up the Trojans game-winning field goal.

Biggest play: Call this the biggest "replay." With four seconds left in the UCLA-Oregon State game, Bruins quarterback Richard Brehaut completed a 12-yard pass to Randall Carroll to put the Bruins in position for a 51-yard field goal. But it appeared the play clock had expired, as the field officials ruled. But the Bruins challenged the call and won, getting 1 more second to play, and kicker Kai Forbath connected for a 17-14 win.

Offensive standout: Stanford quarterback Andrew Luck dominated a good Arizona defense, completing 23 of 32 for 293 yards with two TDs in the Cardinal's 42-17 win. He also ran for 25 yards on three carries and avoided getting sacked even once by a defense that led the Pac-10 in taking down quarterbacks.

Defensive standout: USC linebacker Malcolm Smith, who's missed two games with a knee injury, recorded seven tackles and a sack against Arizona State and he also returned an interception 74 yards for a TD in the Trojans' victory.

Special teams standout: Arizona State's LeQuan Lewis had a 100-yard kickoff return against USC. The return cut the Sun Devils deficit at USC to 29-21 and seemed to ignite a comeback that ultimately fell short.

Smiley face: California, UCLA and USC each have had their heart questioned this year. All three showed heart this weekend while winning games many thought they'd lose.

Frowny face: Arizona State and Oregon State. The Sun Devils mounted a nice comeback but (again) let a game slip away. Lots of what ifs (again). And we are as baffled as coach Mike Riley about the Beavers' spiritless performance at UCLA.

Thought of the week: If Stanford and Oregon keep winning, it seems likely that both Cardinal quarterback Andrew Luck and Ducks running back LaMichael James will get invited to the Heisman Trophy ceremony. The Pac-10 sent two to New York in 2005 (USC's Matt Leinart and Reggie Bush), but the last time two different conference schools produced finalists was 1988 (USC's Rodney Peete finished second to Barry Sanders; UCLA's Troy Aikman was third).

Questions for the week: Is the Pac-1o going to end up top-heavy? It seems like there's a solid chance that Oregon and Stanford will win the rest of their games. But what about everyone else? Arizona is the only other ranked team, and it's got some tough games ahead (USC, at Oregon, Arizona State). It's possible the final rankings will feature two top-five Pac-10 teams and no one else. And could there really be five teams with losing records?
