I'm sure some of you have visions of Taylor Martinez dancing in the end zone of University of Phoenix Stadium, celebrating his 41st rushing touchdown of the year and a Nebraska national championship. Others might have visions of Oklahoma's secondary giving up a league worst 350 yards a game through the air.
Such is the case when all we have to go on is one game. But not matter how good or bad Week 1 went for your team, it's still one game. Things change.
Here's a look at what we thought we knew a year ago at this time:
1) Kansas State was in trouble. An underwhelming 17-14 win against UMass served as Bill Snyder's debut, and he followed it up with a loss to Louisiana-Lafayette. The Wildcats were in for a long year.
Reality: Snyder's favorite offseason activity -- fishing for JUCOS -- paid off when he found Daniel Thomas, a former Florida recruit who eventually led the Big 12 in rushing. Though two FCS teams on the schedule meant Kansas State couldn't play for a bowl, they played for a trip to the Big 12 Championship in their season finale against Nebraska.
2) Missouri was one of the league's most impressive teams. The Tigers dismantled rival Illinois 37-9 in St. Louis in Blaine Gabbert's debut, and while Nebraska beat up on Florida Atlantic, the Tigers looked like the one of the North's co-favorites with Nebraska and Kansas (who could also make this list), in hopes of a divisional three-peat.
Reality: The Tigers gave up 27 fourth quarter points in a home loss to the Huskers in the conference opener, and Gabbert suffered a badly sprained ankle that lingered throughout the year. A second home loss, this time to Baylor, meant a 1-4 start in Big 12 play for Missouri. And looking back on Illinois, the Fighting Ron Zooks finished just 3-9.
3) Oklahoma's offense was hopeless. Without Heisman winner Sam Bradford, Oklahoma struggled under Landry Jones in the second half, scoring just three points and losing 14-13 to BYU. Neither running back, DeMarco Murray or Chris Brown, topped 60 yards rushing. Playing without All-American tight end Jermaine Gresham didn't help, either.
Reality: Ryan Broyles emerged as the conference's best wide receiver, and Jones matured fast. Oklahoma finished the year scoring over 31 points a game, good for fourth in the Big 12 and No. 28 nationally.
4) Baylor was on its way to a bowl. The Bears went on the road and knocked off Riley Skinner and Wake Forest in a smashing encore to Robert Griffin's freshman season.
Reality: One RG3 knee injury later, Baylor was out a superstar and finished with just one conference win, two overall wins short of bowl eligibility.
5) Oklahoma State was finally about to get over the hump. A summer of hype and a preseason top-10 ranking culminated in one of the biggest wins in school history, a solid 24-10 win against No. 13 Georgia at home. That put the Cowboys in the top 5 and on the cover of Sports Illustrated the following week.
Reality: The Cowboys crashed a week later, suffering an upset at the hands of Case Keenum and Houston at home. Kendall Hunter and Zac Robinson both battled injuries during the season, Dez Bryant was suspended, and Oklahoma State suffered decisive 27-point beatings at the hands of Oklahoma and Texas, though it did win nine games and finish second in the Big 12 South.
