Even though Iowa is leading by 10 points, they have 9 turnovers in the half. They have 12 turnovers/game this season. They need to do better controlling the ball.
They finished with 19 turnovers. So they had 10 turnovers in the 2nd half. I would say this is the biggest reason Iowa lost. Iowa usually controls the ball well.
Iowa shot 45%, which is one of the best shooting games they have had. Michigan State played good offense in the second half, I think Iowa couldn't really have done better D in the 2nd half. But they gave the ball up way too much.
