Taking stock of the third week of games in the Pac-12.

Team of the week: Stanford didn't just beat No. 2 USC, it physically dominated the Trojans in a 21-14 victory, the Cardinal's record fourth consecutive win in the series. First, there was the post-Toby Gerhart Era. Then there was the post-Jim Harbaugh Era. Then there was the post-Andrew Luck Era. Maybe it's just the Stanford Era? The Cardinal is now squarely in the Rose Bowl race. And maybe the national title hunt.

Best game: Utah's 24-21 win over BYU wasn't pretty. It wasn't, really, even deserving of a "best" tag. But it was really weird, particularly the ending, and weird is often noteworthy. On a weekend when four games came down to the fourth quarter, the Holy War had the most breathless finish because it had two breathless finishes.

Biggest play: On third-and-10 from the 50 in the fourth quarter, Stanford QB Josh Nunes was under pressure. He scrambled and found himself bottled up and cut off. Yet a player not exactly known for his athleticism juked the USC defense and cut for a 13-yard gain and a first down. Two plays later, he hit TE Zach Ertz for a 37-yard TD and a 21-14 lead, the final margin of Cardinal victory.

Biggest play II: California had No. 12 Ohio State on the ropes. The score was tied with just under four minutes left in the game, and the Buckeyes faced a third-and-7 from their 28-yard line. QB Braxton Miller was forced from the pocket, but the Bears secondary gagged and let Devin Smith get free behind the coverage. The ensuing 72-yard TD pass provided Ohio State its 35-28 margin of victory.

Biggest play III: BYU had a first-and-10 on the Utah 25-yard line, down 10-7 in the third quarter. Lined up in a shotgun formation, QB Riley Nelson wanted to change the play. While he was barking signals, his center delivered the snap, which rolled past an unaware Nelson. Utah's Mo Lee scooped up the loose ball and rambled 47 yards for a TD. The Utes would need those points in a 24-21 win.

Offensive standout: Stanford RB Stepfan Taylor was the best player on the field against USC. He rushed 27 times for 153 yards and a 59-yard TD and caught five passes for 60 yards and a 23-yard score in No. 21 Stanford's upset win over No. 2 Trojans.

Defensive standout: UCLA CB Sheldon Price matched a school record with three interceptions in the Bruins' 37-6 win over Houston.

Special teams standout: Not a lot to choose from. Oregon's De'Anthony Thomas returned four punts for 87 yards against Tennessee Tech, though he did fumble one.

Smiley face: Cal RB Brendan Bigelow brought life to the Bears by doing his best De'Anthony Thomas at Ohio State, rushing for 160 yards on just four carries -- yes, an average of 40 yards per carry! He had touchdown runs of 81 and 59 yards, and both were spectacular. Might he give the Bears offense a weapon that turns around their season?

Frowny face: Can anyone kick a freaking field goal? USC has no kicker, and Arizona, California, Oregon, Stanford and Utah were a combined 1-for-10, with the Bay Area schools going 0-for-6.

Thought of the week: Two of the Pac-12's five unbeaten teams will go down this weekend because of head-to-head matchups. Arizona travels to Oregon, while UCLA plays host to Oregon State. We'll get a better measure of contenders and pretenders this weekend.

Questions for the week: Is Oregon's Thomas ready to make a Heisman Trophy statement against Arizona? The set-up seems perfect: an ESPN game against a questionable defense. With USC and QB Matt Barkley going down, the Heisman race has opened up. Can Thomas be his fancy self and win the affection of the pundits?
