If there’s a lesson to be learned from week two of the college football season, it would go something like this: If there’s one thing that’s for certain, nothing’s for certain.

After a shocking home loss to North Dakota State U. to open the season, Turner Gill and his Kansas Jayhawks bounced back quickly and stunned No. 15 Georgia Tech 28-25.

Oklahoma had an endless amount of concerns after narrowly escaping Utah State 31-24 to open the year, but the Sooners disproved any doubters with a 47-17 dismantling of then-No. 17 Florida State.

And Oklahoma State U. looked like a Big 12 South contender after running back Kendall Hunter rushed for 257 yards in a 65-17 opener win over Washington State U.

The ride on cloud nine was a short one: OSU escaped with a three-point victory over Troy at home this weekend.

Coaches all across the Big 12 can attest to the amount of parity in college football after a rollercoaster of emotions the past two weeks.

That likely won’t end any time soon as conference play opens up with a Texas Tech-Texas matchup in Lubbock on Saturday.

New Tech coach Tommy Tuberville will use this week to work out some kinks his Red Raiders showed in their first two games.

“We’ve had some pluses and minuses,” Tuberville said during Monday’s coaches teleconference.

“We need to find out where we’re at in terms of a football team.”

It comes as no surprise that many of Big 12 schools have had the same problem Tuberville’s run into: competing for all 60 minutes.

“We haven’t played an entire game,” he said.

“We lost our concentration, to be honest. There isn’t any doubt we will have to play four quarters in this game.”

Achieving a victory over the Longhorns, even at home, is a difficult task.

However, U. Texas knows just as well as any other that a team needs to be on its toes every week.

Some Texas fans have concerns about UT underachieving against non-conference foes Rice and Wyoming, but cooler heads like coach Mack Brown have prevailed.

“There’s nothing we can do ahead, and there’s nothing we can do looking back,” Brown said. “Fans can do that, media can do that, but coaches can’t.”

While this week’s marquee matchup will grab most of the attention around the Big 12 region, other teams will have non-conference competition that should grab their own headlines.

The Nebraska-Washington matchup has already generated some buzz after Nebraska topped Idaho 38-17 this weekend.

The victory was full of ups and downs that Nebraska will need to address as NU prepares for touted quarterback Jake Locker and the Huskies in Seattle.

“It’s pretty obvious he’s a heck of a player,” Husker coach Bo Pelini said.

“He can beat you in a lot of different ways.”

The Blackshirts have had some struggles with mobile quarterbacks in the past, so Pelini’s defense will have to prepare accordingly to stop Locker, a dual-threat talent who’s expected to go early in next year’s NFL Draft.

“You have got to rush with discipline and get some pressure on him,” Pelini said. “You have to give him respect.”
