It's here! November 3 has been a day circled by many West coast football fans since the season ended last January. And had Arizona not gone and screwed everything up, this Oregon-USC showdown would still carry national title implications for both teams. Instead, there's a national title hanging in the balance for just one team. The Oregon Ducks. All eyes will be focused on The Coliseum, but Pac-12 fans have a full holiday menu this Saturday. There will be plenty of tricks and treats for some (Utah? Washington? Oregon State?) and freakish ghouls for others (Cal? Arizona State?

The Pac-12 South was expected to be a one-team race in the preseason. USC was a heavy favorite in August but already has two losses in Pac-12 play. The Trojans, UCLA and Arizona State all have two losses within the conference and Arizona isn't far behind with a 2-3 record. 

Arizona, Arizona State, UCLA or USC: Which Team Wins the Pac-12 South?

And then there was one. Most didn't believe Oregon State or USC could make it to the BCS National Championship game, however, they both just kept winning. No more. After tough road losses this weekend, the Oregon Ducks are flying above the rest of the Pac-12 as the lone remaining national title contender. The depth of the league was once again on full display as programs like Arizona, UCLA and Washington prove that the middle of this league is as strong as any league in the nation.

Two unbeatens still remain out West and one will face a major road test this weekend. But a former Pac-12 Player of the Year candidate will return to help the Beavers attempt to stay unblemished against Washington. The Ducks-Buffaloes showdown, however, shouldn't be nearly as competitive. 

This fall is becoming one of the most entertaining seasons of football in the Pac-12 in years. Three top ten teams, two unbeatens, a dozen Player of the Year candidates, one National Coach of the Year front-runner and arguably the biggest game left in college football about to kickoff in two weeks. This league is stacked with great coaches, great quarterbacks and great athletes. And most importantly, a lot of really good football teams.

The desert will be a busy place this weekend out West as both Arizona and Arizona State host huge showdowns. The Wildcats welcome Washington to Tucson in what should be a tremendous Xs and Os contest, while fans all over the nation will finally learn if Todd Graham's Sun Devils are a legit contender in the Pac-12 on national TV against Oregon on Thursday night.

Meanwhile, USC should roll, Oregon State has to hold serve and The Big Game takes over the Bay Area.

Pac-12's Top Storylines to Watch in Week 8:

At the midpoint of the 2012 season, it's time to take a look at the first half and predict how the second half will turn out in the Pac-12.

First-Half Awards

A huge injury to a player of the year candidate. A marquee top 25 showdown in a historic college town. A Thursday night primetime affair. And the former No. 1 team in the nation going on the road. The weekend of action out West has a little something for everybody, there is no doubt, so let's hope it lives up to the hype. On to Week 7...

Pac-12's Top Storylines to Watch in Week 7:

This weekend in college football was the biggest and most volatile to date. However, out West, Week 6 functioned more as an elimination weekend. Utah and UCLA have been all but removed from South Division contention. Washington proved it was still miles from competing with the North Division champs. And while Rich Rodriguez appears to have a solid team in Tucson, Arizona has started its conference slate 0-3, albeit in somewhat unlucky fashion.

USC and Oregon are still on a collision course for Nov. 3. Yet, both divisions appear to be much improved. And what's more interesting is the hierarchy shift in both the North and South that took place last week. Oregon State and Washington could be the top challengers in the North while Arizona State and UCLA look like the best bets to topple USC in the South. UCLA and Oregon State have must-win games this weekend, while Washington's season could be on the line in Eugene.
