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:

Each week, the Athlon editors and others who closely follow college football vote on the most prestigious award in the sport. A 13-man conglomerate of college football gurus from Athlon Sports and other publications cast their votes this week for their top Heisman Trophy candidates. The votes will be tallied and the results will be posted as the Athlon Sports Heisman Watch List every week of the regular season.

With the completion of Week 7, the first half of the 2012 college football season is officially in the books. As expected, there have been plenty of surprises from the first two months of action and no shortage of preseason picks gone awry. With West Virginia's loss on Saturday, the race to win the Heisman Trophy is wide open, with Ohio State's Braxton Miller taking a slight lead over Geno Smith. Alabama and Oregon are the favorites to play for the national championship, but both teams still have plenty of hurdles left to clear the rest of the way.

With the first release of the 2012 BCS Standings, Athlon Sports wants to make sure fans are aware of some stats, trends and rankings when sifting through the debut of the rankings that will eventually determine who will play for the national championship.

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

The first BCS standings for 2012 began where they ended in 2011 -- with an all-SEC title game scenario.

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:

It is never too early to begin looking ahead to next year’s NFL Draft. Each year a unique set of prospects enters the professional ranks with a chance to make an immediate impact on the country’s most powerful sport. The 2013 NFL Draft won’t be any different.

Today, we rank college football best running back prospects:

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.
