Omaha, Neb. ? There’s some flipping and flopping going on in the Big 12 North.

The flipping? Kansas University and Colorado. Those two were picked to finish in the lower half of the division, but they are off to 2-0 starts and are the only unbeaten teams in the North.

The flopping? Kansas State, Missouri and Nebraska. The three were predicted to finish 1-2-3 in the division, and each suffered embarrassing losses in the second week of the season.

The turnabout in the North has led to the Big 12 having only two teams ranked this week in the Associated Press Top 25 — the fewest since the league started in 1996.

The only ranked teams are No. 2 Oklahoma and No. 6 Texas.

Previously, the fewest number of ranked Big 12 teams was three. Last week, there were four in the top 25, but Kansas State and Missouri no longer are among the elite.

Kansas followed its easy season-opening win over Tulsa with a 63-14 rout of Toledo. The Jayhawks go for three in a row this week at Northwestern.

Colorado, coming off a spring and summer of sex and recruiting scandals, struggled on offense, but parlayed touchdowns off an interception return and blocked punt into a 20-12 road win over Washington State. The Buffaloes try to extend their win streak at home against North Texas.

Defending conference champion Kansas State (1-1) is reeling after its 45-21 loss at home to Fresno State. That followed a harder-than-expected, 27-13 win over Division I-AA Western Kentucky in the opener.

The Wildcats can take solace in knowing that they struggled to a 4-3 start last year — including three straight losses — before winning seven in a row to claim their first Big 12 title.

Senior tight end Brian Casey said he would remind his younger teammates about how last season played out.

“We did the same thing last year, and, like coach (Bill Snyder) said, we still have our destiny in our hands,” Casey said. “We can still go all the way. The teams in the national championship game last year had a loss, too.”

Like K-State, Nebraska lost a home nonconference game for the first time since 1991.

The Cornhuskers fell victim to five turnovers in a 21-17 loss to Southern Mississippi. The Golden Eagles converted three Joe Dailey interceptions and a Dailey fumble into 18 points.

What frustrated the Huskers most about the loss to Southern Miss was that they nearly doubled the Eagles’ offensive yardage (476-239).

“There were a lot of good things done on the field,” Nebraska coach Bill Callahan said. “I felt we improved in certain areas of our play, and it’s just really disappointing and unfortunate to see our players have a game taken away by themselves.”

Nebraska, which visits Pittsburgh on Saturday, is off to a 1-1 start for only the second time since 1985.

Missouri (1-1), which many had predicted for a breakthrough year, suffered a major setback in losing 24-14 at Troy on Thursday.

Iowa State, which ended a 10-game losing streak with last week’s shutout of Northern Iowa, played then-No. 12 Iowa tough before losing, 17-10.
