Without a doubt, last Saturday may have been the most shocking loss suffered by the Oklahoma Sooners in quite some time.

The Sooners lost as the No. 3 ranked team in the country, a team that had already gone into vaunted Ohio State and won. OU lost as a team favored to win by at least 30 points. The Sooners lost to a team it has pretty much owned going back to the Bud Wilkinson days. They lost to a team that was playing its third-string quarterback.

So now what, in the aftermath of Iowa State 38, Oklahoma 31? Did the chance to reach the College Football Playoff go by the wayside? Is OU still considered the best team in the Big 12? You can answer both yes and no to those questions.

Nine times out of 10, the Sooners beat Iowa State. But that's the beauty of sports, you just never know sometimes. Ask the United States men's soccer team about that.

But as an OU fan, all hope is not lost. We've seen this time and time again, that a shocking regular-season loss doesn't mean the world is coming to an end, not just at Oklahoma but college football in general.

Last year, Clemson was shocked at home by a so-so Pittsburgh squad. Did that knock the Tigers out of the playoff picture? No, they bounced back to win the Atlantic Coast Conference, beat Ohio State in the semifinals and avenged the loss the previous season to Alabama to win the national title.

Speaking of Alabama, remember in 2012 when the Crimson Tide were shocked at home by Texas A&M in Johnny Manziel's coming-out party? That was later on in the season, and Alabama's chances of repeating as BCS national champs appeared slim. But the Tide bounced back, and managed to repeat after all. Alabama also lost at home in both the 2011 and 2015 seasons and still somehow ended up winning the whole thing.

OU's playoff chances probably took a big hit with the Iowa State loss, even if the Sooners win out and end up winning the Big 12 title. But who's to say a similar upset can't happen to any of the other teams contending for a national title, and that as long as the Sooners take care of their business, they can still sneak in through the back door?

In this day and age of college football as we know it, upsets are bound to happen. Sometimes it helps to have a little luck on your side.

If you're Oklahoma, you just try and shake off last week and move on to this Saturday's renewal of the annual grudge match with Texas. A Texas team which is undefeated in conference play so far, and oh yeah, a team that held Iowa State to seven points.

But that's all in the past. An Oklahoma win against Texas can go a long way toward curing a bunch of ills. And if the Sooners get past the Longhorns, OU still has undefeated TCU, improving Texas Tech, Oklahoma State and West Virginia still left, and should OU reach the Big 12 championship game, that's another chance to enhance the ol' resume. If the Sooners run the table, who knows.

And if you're an OU fan, just go back two years, also in the month of October. The Sooners were undefeated and riding high before getting upset by a team which was coming off a 50-7 loss the week before, a team which ended up going 5-7.

That team was Texas. The Sooners bounced back, ran the table, won the Big 12 and still made it into the College Football Playoff.

So can history repeat itself? We'll see.

But first things first, the Sooners are, to paraphrase New England Patriots' coach Bill Belichick, moving on to Texas. Keep winning, and let the rest take care of itself.

And a little help and a few more shocking upsets wouldn't hurt, either, if you're an OU player, coach or fan.
