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.

This league seems to get deeper and deeper each Saturday. After another stellar weekend of action out West, six Pac-12 schools now reside in the AP Top 25. Washington and UCLA slide into the rankings, while Arizona State is knocking on the door and Arizona is clearly another solid team. And as strange as it may sound, Cal might be the best 1-4 team in the nation.  

College football’s Week 5 action features a key showdown in the Big Ten, West Virginia’s first-ever Big 12 game and Texas’ trip to Stillwater to battle Oklahoma State.

Otherwise, all eyes across the college football world should be on the Pac-12 this Thursday evening.

Pac-12's Top Storylines to Watch in Week 5:

Oregon and USC used stellar defensive performances to get key home conference wins. Oregon State and Mike Riley shocked the country once again with an upset win over a ranked opponent — this time on the road — as the Beavers have added their name to the crowded North Division race. The Colorado Buffaloes got what could be its first and only win of the 2012 season in stunning fashion. But the most startling performance of the weekend has to go to Todd Graham and the Arizona State Sun Devils.

Stop if you’re heard this: Florida State and Notre Dame are back.

Though they’ve fooled us before, the Seminoles and Fighting Irish sure looked like potential title contenders as they emerged as the big winners in a busy slate of primetime games Saturday.
