“This was really, really needed,” Gottlieb said. Iowa (18-3, 9-1) turned the ball over nine times in the first half and USC scored 13 points off of those turnovers to build a 43-37 advantage by halftime. USC shot 6 for 17 from 3-point range in the first half and 10 for 27 for the game. Dunn shot 3 for 6 from long range in the first half and already had 16 points by the intermission. USC starting forward Vivian Iwuchukwu exited the game with an apparent injury with 7:50 left in the fourth quarter.
