​Despite a pretty quiet night of college basketball, the Big 12 made big noise with two significant upsets in the conference.

First came Kansas State's road win over No. 20 Oklahoma, and then unranked Iowa State followed suit with an impressive 68-64 road triumph over No. 8 Texas Tech to further shake things up in the Top 25.

Iowa State was coming off a deflating home loss to Kansas State this past weekend, which booted them out of the rankings, but they've regained their footing with a victory over one of the best teams in the country. The Cyclones had four players with double-digit points, including Marial Shayok, who led the team with 20.

As for Texas Tech, the Red Raiders didn't bring their patented defense to the floor on Wednesday night, allowing Iowa State to shoot 45 percent from the floor. What really did them in was their 6-of-15 night from the free throw line, solidifying their first conference loss of the year.

While Texas Tech guard Jarrett Culver poured in 20 points and snagged 16 rebounds, he was just 7-of-21 from the field and 5-of-10 from the charity stripe.

The Big 12 Conference is arguably the most competitive in the NCAA, and Iowa State and Kansas State proved that the narrative is continuing early on this year.
