If there's one thing I know about basketball courts, it's that they need to provide an ideal playing surface. Otherwise, they're no good. So, with this in mind, Big 12 commissioner Brett Yormark decided to pull the plug on his conference tournament's LED glass floor late Thursday in advance of Friday's semifinals.

"After consultation with the coaches of our four semifinal teams, I have decided that in order to provide our student-athletes with the greatest level of comfort on a huge stage this weekend, we will transition to a hardwood court for the remainder of the tournament," Yormark told CBS Sports' Matt Norlander. "We look forward to a great semifinals and championship game."

To be clear, not everybody complained about the court being slippery; some seemed comfortable on it. But players were noticeably slipping at different points in different games. And after Texas Tech's Christian Anderson was injured midway through Thursday's loss to Iowa State, Yormark made the call.

And I give him credit.

Yormark is a big-thinker with big ideas -- one of which was this. It looked cool. It created a buzz. But it wasn't working the way it needed to work. So rather than have it overshadow two tremendous semifinals on tap, it made sense for Yorkmark, as uncomfortable as the whole thing might've been, to swallow whatever pride was attached to this high-tech look, change course and get a traditional hardwood court installed.

Now, here's Friday's schedule:

* 7 p.m. ET: Arizona vs. Iowa State

* 9 p.m. ET: Houston vs. Kansas

Those four teams are No. 3 (Arizona), No. 5 (Houston), No. 9 (Iowa State) and No. 15 (Kansas) in Friday morning's updated CBS Sports Top 25 And 1 daily college basketball rankings, where Duke remains No. 1 for the 20th straight day.

Duke will play Clemson in the ACC Tournament semifinals on Friday. If the Blue Devils win, they'll either play Virginia or Miami in Saturday's title game.
