Rivals.com put together its best and worst moments from the first half of college football.

5 MOST IMPORTANT THINGS WE’VE LEARNED
1. THE BIG 12 IS THE NATION’S BEST CONFERENCE. Yeah, yeah, defense wins championships. But the offenses in this conference would cause a video game to short-circuit. Never before has one conference had so much firepower. As we turn the corner on the halfway mark, the Big 12 has four teams –Texas, Oklahoma, Texas Tech and Oklahoma State – ranked in the top 10. And Missouri and Kansas are in the top 20.

5 THINGS WE’RE STILL WAITING TO LEARN
2. IS NOTRE DAME BACK? The Irish are 4-2. But, honestly, who have they beaten? Even if the Fighting Irish march on to finish 9-3, we won’t know how good this program is until next fall.

5 BEST MOVES
3. OHIO STATE HANDS ITS OFFENSE TO TERRELLE PRYOR. It took some guts to hand the starting quarterback job to a true freshman, particularly since incumbent starter Todd Boeckman had directed the Buckeyes to a BCS Championship Game appearance. But Ohio State has looked like an entirely different team with Pryor at the helm.

5 WORST MOVES
1. AUBURN SWITCHING TO THE SPREAD OFFENSE. Auburn has the type of championship-caliber defense that could have made the Tigers a top-10 team as long as their offense was merely competent. Switching to the spread when you don’t have players suited to that offense assured Auburn would waste all the talent it had assembled on the other side of the ball.

2. TYRONE WILLINGHAM, WASHINGTON. It’s not if but when he will be asked to turn in his keys. When he leaves, Willingham can know he has left the place better than he found it.

And speaking of the disaster that is Willingham and Washington, the Huskies are 42-point underdogs at home this Saturday against USC. Forty-two point underdogs…at home…and the Trojans are probably a lock to cover…seriously.

Time to check out the big games, top matchups and potential upsets as college football heads into Week 3.

Top 25 Action:
No. 5 Ohio State (2-0) at No. 1 USC (1-0), Saturday 8:00 PM ET ABC
OSU head coach Jim Tressel said Tuesday that Heisman candidate Beanie Wells will play Saturday in Southern Cal. The Buckeyes are going to need all the offensive firepower they can get against one of the best front sevens in the nation. USC quarterback Mark Sanchez shredded Virginia for over 300 yards and three touchdowns in Week 1, but OSU’s defense is loaded with experienced talent. This is one of the most anticipated college football games of the year and should be a tight contest, although oddsmakers have made the Trojans 10.5-point favorites. (Check out our offical Ohio State-USC smack talk thread as well.)

No. 13 Kansas (2-0) at No. 19 South Florida (2-0), Friday 8:00 PM ET ESPN2
This is a tremendous matchup to kick off the Week 3 schedule as Kansas and its high-powered offense take on South Florida, which has the No. 1 ranked defense in college football. In their two wins, the Jayhawks averaged over 450 yards a game, but they go up against a Bulls’ defense Friday night that has only allowed an average of 161.5 yards per game. Oddsmakers have listed South Florida as a 3-point home favorite.

No. 10 Wisconsin (2-0) at No. 21 Fresno State (1-0), 10:30 PM ET ESPN2
Marshall rolled out to a 14-0 lead on the Badgers last week before Wisconsin eventually settled down and hammered the Thundering Heard 51-14 to improve to 2-0 on the year. Fresno State dismantled Rutgers 24-7 in New Jersey in Week 1 and should be well rested coming off a bye last week. One thing to keep an eye on is the health status of Wisconsin TE Travis Beckum, who missed the Badgers’ first two games this year with a bad hamstring. Beckum is highly regarded as one of the top tight end prospect in college football and is expected to play this weekend.

No. 2 Georgia (2-0) at South Carolina (1-1), Saturday 3:30 PM ET CBS
Before being upset by Vanderbilt last week, the Game Cocks were supposed to be Georgia’s first real test of the 2008 season. One has to assume that South Carolina is going to come out fired up after being bounced from the top 25 following their loss to the Commodores. The Bulldogs absolutely hammered Central Michigan last week, but can’t take anything for granted this Saturday playing a pissed off Steve Spurrier squad. SC is a 7.5-point home underdog.

Upset Watch:
UCLA (1-0) at No. 18 BYU (2-0)
Washington gave BYU all it could handle in Week 2 before the Cougars eventually eked out a 28-27 win. And the last time we saw the Bruins, they were upsetting Tennessee in the first week of the season. While this wouldn’t be a huge upset, it would be the second time in two chances that UCLA knocks off a ranked opponent. And with Fresno State, Oregon, California, ASU and USC on their schedule, the Bruins will have plenty of opportunities to make some noise and possibly become one of the best surprises of the season. BYU is currently an 8-point favorite.

Other notable games:
No. 14 East Carolina at Tulane – Saturday, 3:00 PM ET
No. 3 Oklahoma at Washington – Saturday, 7:45 PM ET
Arkansas at No. 8 Texas – Saturday, 3:30 PM ET

FOX Sports.com complied 25 questions facing teams heading into the 2008 College Football Season. Below is the top two; click the link above to see all top 25.

1. Is Ohio State really on target for a third straight shot at a national title?
Start getting used to the notion of the Buckeyes being favored to return to the BCS Championship game, looking for redemption after losing badly to Florida and LSU in back-to-back tries. Ohio State is absolutely loaded with talent and has a massive scarlet and gray chip on its shoulder. A consensus favorite in the Big Ten, the Bucks will get tested in the league, but gets their best chance to quiet critics with a Sept. 13 trip to USC. Without nitpicking, it’s hard to find a glaring weakness other than the national perception. Now all Ohio State has to do is get back to another title game and close the deal this time.

2. How will Georgia manage a nasty schedule and a year-long target on its chest?
As far back as last November, Georgia was being considered a presumptive favorite for the 2009 BCS championship. Back then, the Dawgs were too young and having too much fun to think about expectations. This fall, they’re going to hear about it from fans and the media every single day. While there’s certainly enough talent to come through, the Bulldogs will have to prove they can handle an immense amount of pressure and scrutiny, while navigating a slate that includes trips to South Carolina, Arizona State, LSU and Auburn, visits from Alabama and Tennessee, and one titanic game with Florida in Jacksonville.

If the Buckeyes beat (I hesitate to use the word “upset” because the programs are 2-3 in the polls) USC, they should be on easy street the rest of the year. The Big Ten is a joke, even though Wisconsin is a solid program. The Badgers are incredibly beat up (especially on the defensive line) for this early in the season and even though they’re OSU’s biggest threat in the conference, the Buckeyes still have the better talent.

And it’s going to be hard for Georgia to stay atop the polls all season. Not only do they have a brutal schedule, but also the offensive line is largely inexperienced and it might take time for the unit to gel with two ’07 starters switching positions. The Bulldogs are loaded with talent, but they’ve got a minefield ahead of them playing in the SEC.
