"We just didn't come ready to play," quarterback Jerome Tiller said. "They played better and wanted it more than we did."
Coach Paul Rhoads said early in the week the game would come down to turnovers and it did.
"We executed poorly over the course of the football game," Rhoads said. "At halftime, we were a victim of our own mistakes, and in the second half, we had to play too much catch up.
"We have to learn how to win football games and that is what we need to work on," Rhoads said.
The game started ominously for both offenses actually, as Iowa (2-0) signal caller Ricky Stanzi was picked off by David Sims, but Tyler Sash got the ball right back for the Hawkeyes by swiping one from Arnaud. Iowa State was able to stop Iowa in Cyclone territory to keep the game tied though.
After an Iowa punt, the Cyclones got their running game going and Arnaud made a key throw to Derrick Catlett, as Iowa State took the lead 3-0 on a 46-yard field goal by Grant Mahoney. Iowa State then tried to surprise the Hawkeyes with an onside kick but it did not work and Iowa got good field position.
Stanzi gave Iowa the lead for good when he hit Brett Morse from one yard out. Iowa forced a quick three-and-out and drove the ball right back down into the red zone, Sims intercepted Stanzi at the four and returned the ball to the 45.
After an exchange of punts, Arnaud was intercepted again by Sash and that led to a 18-yard touchdown pass from Stanzi to Darrell Johnson-Koulianos. Arnaud threw his third pick of the half to Brent Greenwood just before the half as the Cyclones were driving.
Another thing Iowa State struggled with was penalties, committing nine for 79 yards in the game after just one penalty a week ago. Six of those came in the first half and shut down drives, along with keeping them from getting started.
"We committed far too many penalties," Rhoads said. "It's not that we are any less disciplined this week; we just have to show better control."
Arnaud said the team just hurt themselves too much.
"We were moving the ball just fine," Arnaud said.
Iowa State got a couple of first downs on its first drive of second half but Alexander Robinson, who had 100 yards on the day, fumbled at the ISU 48. Iowa then made it 21-3 on a 7-yard Stanzi-to-Allen Reisner touchdown pass. On the next series, Arnaud was intercepted again by Greenwood and Stanzi to Trey Stross for 39 yards to set up a Brandon Wegher short touchdown plunge to make it 28-3.
"Austen was ineffective and turned the ball over too many times," Rhoads said. "I think he surprised he was in the game one interception longer than he was.
"They did do a nice job of disguising their coverages and we didn't adjust well," Rhoads said.
Arnaud said he let the Iowa defense and their disguised coverages bait him into a couple of bad throws.
"I take full blame for that game, because we turned the ball over way too much," Arnaud said. "Today I had a bad day, but I can't afford to have bad games for our team."
Jerome Tiller then took over for Arnaud, and on his second possession, had the Cyclones moving before being picked off by Sash. Wegher, a true freshman who had a game-high 101 yards in his first game, led Iowa on its last touchdown drive, which was capped by a Stanzi to Keenan Davis six-yard touchdown strike.
"We knew there would be opportunities for interceptions, we just didn't know who was going to get them," said Sash, who also had a team-high 10 tackles and a forced fumble. "Our defense played well, our offense played well and we got the job done."
