But Spangler helped put the Sooners right back on top, bulling his way into the paint, hitting a contested shot and drawing a foul.
“I just needed to be smart,” Spangler said. “You're going to have games like that where you get into foul trouble. I need to keep my head up better than I did last game but every game's a new game and I just have to come out with the same approach.”
The Sooners, who came in struggling on the defensive end, then followed that up with one of their best defensive possessions of the game.
For much of the shot clock, Buddy Hield kept DeAndre Kane from getting a good look at the basket. As the shot clock ticked down, Kane passed it to Ejim in the corner and Ejim had to throw up a desperation 3-pointer as the clock expired.
Ejim's shot didn't hit anything but the rebounding Cameron Clark's hands, and Iowa State never had the ball with a chance to tie or take the lead again.
“Coach was preaching to us, ‘We need stops, we need stops,'” Hield said. “I was on Kane and got a good switch.”
Hield scored 22 points, including a career-high six 3-pointers. The sophomore guard has 62 points in the last three games.
Isaiah Cousins added 17 points off the bench.
Kane led Iowa State with 23 points while Ejim added 21.
