Pac-12 Week 9: Did you know?

Some notes to get you through the hours until Saturday. Thanks to ESPN Stats & Information for many of these numbers.

  • Colorado leads the series with Arizona 13-2, but the Wildcats won 56-31 last year in Tucson. The Wildcats did lose 49-29 to the Buffaloes in 2011, the last time they were in Boulder and their first meeting as members of the Pac-12's South Division.

  • Arizona RB Ka'Deem Carey now leads the nation with 161 yards rushing per game. He is coming off a season-high 236 yards rushing in the win over Utah. He led the nation in rushing in 2012. With 3,159 career rushing yards, he also is just five yards from moving into fourth place on the Wildcats' all-time list. The last time he faced the Buffs, he rushed for a Pac-12 record 366 yards and five touchdowns. That game was Arizona QB B.J. Denker's first career start.

  • Colorado freshman RB Michael Adkins II rushed for 137 yards (10.5 avg.) and a school freshman record four TDs in the win over Charleston Southern.

  • Washington leads the series with California 51-38-4 in a series that began in 1904. Washington and California are the only two teams that have played in what is now the Pac-12 Conference in every season since the league was founded in 1916. The Huskies have won four straight in the series, including 21-13 last year in Berkeley.

  • The big question for Cal this week is who the starting quarterback should be, as true freshman starter Jared Goff has been ineffective since Pac-12 play began. He has twice been replaced by redshirt freshman Zach Kline.

  • The Huskies will pay tribute to legendary former head coach Don James, who passed away Sunday at the age of 80. James coached the Huskies from 1975 to 1992.

  • Huskies QB Keith Price moved into the No. 2 spot in career passing yards for Washington last weekend against Arizona State. He now has 7,746 career yards, having moved past Jake Locker (7,639).

  • The Bears rank 112th or worse in the nation in: rushing offense, total defense, scoring defense, turnover margin, pass efficiency defense and penalty yards per game.

  • The combined record for the six opponents that have defeated Cal this year is 31-5. The Bears have lost nine consecutive Pac-12 games.

  • Oregon has scored at least 45 points in each of its first seven games this season, the first major college football team to do that since Harvard in 1887. UCLA has the second-best scoring defense in the Pac-12 and hasn't allowed more than 27 points in any game this season.

  • Oregon QB Marcus Mariota continues to garner Heisman support this year and was ranked No. 1 in ESPN's Heismanology Poll heading into last week's games. He leads the nation in Opponent-Adjusted QBR at 96.6 and yards per rush at 10.1. Among qualified quarterbacks, he and Nevada's Cody Fajardo are the only FBS quarterbacks without an interception this season, and Mariota ranks fifth nationally with 19 touchdown passes. He's gone 265 attempts without an interception, a Pac-12 record.

  • Oregon leads the FBS with 40 touchdown drives in 2 minutes or less, five fewer than they had all of last season. Since Chip Kelly left for the NFL, Oregon has not missed a beat. The Ducks are averaging about eight more points per game and scoring touchdowns at a higher rate in 2013 (51 percent) than 2012 (43 percent). In the first half, Oregon is averaging 18 seconds per play and has scored and FBS-high 26 of its 33 offensive touchdowns in 2 minutes or less.

  • These teams last met in that 2011 Pac-12 title game. Oregon has won the last four meetings overall and hasn't lost to UCLA at home since 2004. The Ducks are looking for their first five-game win streak against UCLA.

  • Should Oregon be concerned in this game? ESPN's College GameDay is visiting Eugene this week. Teams that have hosted GameDay this month are winless (0-6) since hosting the show.

  • Third-down conversions have been key for the Bruins on both sides of the ball, where they rank in the top 10 in third-down conversions and third-down conversion defense. The only other teams ranking in the top 10 in both categories are Louisville and Florida State.

  • UCLA must cut down its penalties, especially against tougher competition. The Bruins are averaging 9.7 penalties per game, the most of any FBS team, and their penalty margin is second-worst among all FBS teams (committing 22 more than their opponents). But Oregon isn't much better in that category. The Ducks average 8.0 penalties per game (tied for seventh-most in FBS), and have been flagged 18 times in the last two games (9 each).

  • UCLA beat then-No. 23 Nebraska on the road earlier this season. The Bruins haven't won multiple road games over ranked opponents in a season since 2001.

  • UCLA hasn't beaten an AP top-five team on the road since 1990 (at No. 2 Washington). Since then, the Bruins have lost six straight such games, losing by an average of 32.8 points per game.

  • Oregon State and Stanford have met all but one season since 1967 (2001) and Stanford has won three straight and four of the last five meetings (Oregon State had won six of the previous seven). The Cardinal haven't won at least four straight against the Beavers since winning six in a row in the series from 1990-95.

  • Oregon State QB Sean Mannion leads the FBS with 29 TD passes and 2,992 passing yards. Since 2000, only three quarterbacks have had more TDs and only two have had more passing yards through the first seven games of a season. Looking ahead, Texas Tech's B.J. Symons also had the most of each through eight games since 2000 (36 and 3,914 in 2003).

  • Oregon State is tied for third in the FBS with 56 plays of at least 20 yards this season, and it's thanks to Mannion. Mannion has 53 completions of 20 yards or more in 2013, most in the FBS and the most by any FBS player through seven games over the last 10 seasons.

  • Oregon State is facing a team ranked in the Top 10 of the BCS Standings for the 18th time. The Beavers have lost seven straight matchups with BCS Top 10 teams and 14 of the previous 17 overall. The lone wins came in 2000 vs. No. 7 Oregon, 2001 vs. No. 8 Washington, and 2006 vs. No. 3 USC.

  • Stanford comes in at No. 6 in the BCS Standings, and that's a good thing for the Cardinal. Stanford has won eight straight games while ranked in the BCS, including four wins against teams that also were ranked in the standings at the time of game. The Cardinal's last loss while ranked in the BCS came in the 2012 Fiesta Bowl (2011 season) against No. 3 Oklahoma State.

  • USC leads the series with Utah 8-3, and just one of those Utes victories -- the 2001 Las Vegas Bowl -- came since 1916.

  • The Trojans beat the Utes 38-28 last year in Salt Lake City. Utah's debut as a Pac-12 member was against USC in the Coliseum in 2011, a 23-14 loss. Trailing 17-14 with 11 seconds left in regulation, Utah had a chance to send the game into overtime, but Coleman Petersen's 41-yard field goal attempt was blocked and returned for a touchdown. It was a memorable ending, because the Pac-12 officials never made it clear to anyone whether the touchdown counted, forcing the conference to put out a press release to change to final score.

  • Utah leads the Pac-12 in sacks (22) and sack average (3.14), ranking 11th in the nation. The Trojans have yielded 15 sacks.
