The team was rocked with news this week that All-Pac-10 cornerback Michael Jolivette will be lost for at least the majority of the season with a sprained MCL and damage to both his ACL and PCL. Jolivette was vital to the team's double-eagle flex defensive scheme, which relied on lots of man-to-man in the secondary to free up linebackers for blitzing and run-stopping. In his absence, redshirt freshman Darrell Brooks will move over to the No. 1 corner spot and nickel back David Hinton will move into the No. 2 role.

Following in the footsteps of his older brother Trung, Cornell Canidate is quickly becoming a collegiate star in Arizona. The ASU freshman has jumped from No. 3 to No. 1 on the depth chart in the backfield, stepping over Mike Williams, last year's starter, and Hakim Hill, the most touted running back recruit in the history of the program. Canidate stands to be the first freshman to lead the Sun Devils in rushing since 1955. Trung, who now plays for the St. Louis Rams, was a former standout for in-state rival Arizona, and led the nation in rushing as a standout at Arizona in 1999

Last week: Lost to Air Force 23-21
This week: No. 16 Washington State (3-1)

Faster than you could say "ranked for the first time since 1996," the Bears dropped off the national radar with a shocking loss to Air Force Saturday. But Cal won't have to wait too long to get their chance for redemption - this week's game against WSU can make the difference between a great season (and a spot in the Top 25 again) or another year as the conference cellar-dweller. At least the Cougars don't run the flexbone.

No. 9 Oregon (4-0)
Last week: Beat Portland State

With a week's break before the conference opener against Arizona, head coach Mike Belotti has singled out penalties as his team's No. 1 problem right now. He said it's the most-penalized Ducks team he's ever coached, and plans to spend the week with his assistants going over tape of every infraction and trying to figure out the source of the problem.

No. 23 Oregon State (4-0)
Last week: Beat Fresno State 59-19
This week: No. 18 Southern California

Uh oh, it looks like "Miami East" is back after a blowout victory over the Bulldogs. Coming into the season, head coach Dennis Erickson said defense would be the strength of this year's squad, but last week it was the running game making all the headlines. Tailback Steven Jackson rolled over what was thought to be a tough defense against the run, racking up 227 yards and two touchdowns en route to being named Pac-10 Offensive Player of the Week.

No. 18 Southern California
Last week: Lost to Kansas State 27-20
This week: No. 23 Oregon State (4-0)

The Trojans will have to deal with the ignominy of being the Wildcats' first home victory against a ranked opponent · ever. But the players said they're confident this is going to be a big year for USC despite the loss. The defense, considered one of the best in the country heading into Manhattan last Saturday, is still the best unit the program has fielded in some time, and it looks like Carson Palmer is close to living up to the hype. All that's needed is a statement against Oregon State this weekend for voters to forget about the slip-up against KSU.

This week: Arizona State (3-1)

His name isn't Rudy, but Greg Camrillo is getting some walk-on love with the Cardinal this season. The sophomore was a non-scholarship scout-teamer last season, but this year's he's getting considerable playing time at the wide receiver position. Coaches love his work ethic and route-running, and plan to use him more as the season progresses. The only thing ruining a perfect Hollywood script is that Camarillo isn't technically a walk-on anymore - this week his scholarship was finalized, so he'll be attending Stanford on the school's dime.

Apparently, the bottle wasn't a problem isolated to Cory Paus last season for the Bruins. This week, some players stepped up to bat and publicly said too many of their teammates spent their Thursday nights/Friday mornings last season livin' la vida loca, and it hurt their performance on the field. Paus is, ironically, one of the leaders of the charge for players to eschew the nightlife. He's said he's been sober for four months after two DUIs forced him to spend some time in the pokey, and now's he's ready to lead by example and encourage his teammates to stay sober on game weeks.

No. 13 Washington (2-1)

This week: Idaho (1-3)

Despite boasting the third-best passing offense in the NCAA, head coach Rick Neuheisel said he plans on keeping the option a part of the Huskies' offense this year. At the outset of the season, Neuheisel said he would run the running offense less to protect his quarterback, Cody Pickett, who suffered a separated shoulder last year. But now the coach says it was a ruse all the time, and that even Pickett is looking forward to the myriad keepers and pitches that come with the old school offense.

No. 16 Washington State (3-1)
Last week: Beat Montana State 45-28
This week: California (3-1)

The good news for Cougars fans is that quarterback Jason Gesser didn't suffer either a torn rotator cuff or a separated shoulder, the two leading choices in the "guess the season-ending injury" game that started after the senior was knocked out of last week's win over Montana State. Instead, Gesser suffered a dislocated rib, which means he could be ready to go against the Golden Bears this weekend.
