Here are 10 things I'm keeping an eye on in Week 2 across the Big 12.

1. Collin Klein's workload. The big man only got 12 carries a week ago. Was it because Bill Snyder knew his team could handle FCS Missouri State, or can we expect more of a change out of Kansas State's offense? I'm betting on the former, but you never know what to expect from Bill Snyder. No coach in the league plays his cards closer to the vest.

2. Oklahoma's passing game. It was a little bit of everything last week against UTEP. Receivers looked uncomfortable and didn't always get open. One long pass was called back because the receiver stepped out of bounds. The offensive line wasn't great in protection, but Landry Jones held on to the ball a little too long on plenty of occasions. The Sooners know they need to fix the problems. Playing against an FCS opponent is a good time to get some work in.

3. Steele Jantz's decision-making. Jantz was much more judicious with the ball in Week 1 against a decent Tulsa team than he was in the first few games of last season. Will that continue? His one interception last week was partly his fault (poor accuracy) and partly his receiver's fault (tipped pass). Iowa State can't afford turnovers against Iowa.

4. Wes Lunt under fire. Mike Gundy liked what he saw from Lunt, but knows Lunt didn't face third-and-longs, blitzes or pressure of any kind. That'll change this week against former WVU defensive coordinator Jeff Casteel, now in Tucson. You have to assume Arizona's game plan centers around pressuring the freshman quarterback. You can't drop back and see if the backs can beat you -- they can. How does Lunt handle it? Oklahoma State's hopes hinge on it.

5. Kansas' defensive line. The Jayhawks had just nine sacks a year ago, but defensive linemen got two against South Dakota State last week. But KU also gave up a 99-yard touchdown run. What does the unit most in need of a facelift from 2011 have in store for Week 2?

6. TCU's defense. I don't think the Frogs can really prove anything, but I'm mostly curious about who's going to be where and how often for the Frogs. Gary Patterson shook up his defense during fall camp, and TCU has two freshmen starting on the defensive line. How do the new safeties look? Here's guessing that depth chart changes even more after Week 1.

7. Texas' defensive miscues. Safety Kenny Vaccaro said players on defense played as if they'd read too many of their press clippings last week. The defense gave up an 82-yard touchdown to Wyoming and looked undeniably mortal for a unit that's supposed to be the Big 12's best. Will the Longhorns eliminate mistakes this week against New Mexico?

8. Texas Tech's first quarter. The Red Raiders looked sluggish against FCS foe Northwestern State last week, leading just 7-3 early in the second quarter. This week, they have a road game against Texas State. I think Tech wins, but starting slow and falling behind to the Bobcats would energize the crowd and the team in a game it wants badly. Tech needs to open the game with its best. At halftime of last year's matchup, Texas Tech led this game in Lubbock 10-9.

9. Big 12's first loss of the season? The Big 12 mostly cruised through Week 1, save for Iowa State's first quarter against Tulsa. The conference faces three major tests in Week 2, though: (1) Oklahoma State has to take care of business on the road against Arizona; (2) can Kansas State take the first step in validating last year's 10-win season against Miami? The most likely spot for a loss? and (3) A toss-up game at Iowa for Iowa State. Getting through two weeks of football at 17-0 is definitely possible for the Big 12, though.

10. Oklahoma State's renewed defense. The Cowboys have the personnel to be solid this season, but are they as good as advertised on defense? Arizona's zone-read scheme is an interesting test -- mostly for the front seven. The Cowboys linebackers are solid, but can the defensive line prove itself? I'm looking at Cooper Bassett, Nigel Nicholas and Calvin Barnett on this one.
