(AP) -- Nearly everyone assumed Iowa would lean on senior quarterback James Vandenberg until the rest of the offense found its footing under new coordinator Greg Davis
One week into the season and the Hawkeyes' stagnant passing game is a major concern with Iowa State (1-0) visiting Kinnick Stadium on Saturday.
Iowa (1-0) survived a fierce test from Northern Illinois last weekend, beating the Huskies 18-17 on running back Damon Bullock's 23-yard touchdown late in the fourth quarter.
Bullock rushed for 150 yards, easing concerns about who would handle the bulk of the carries for the depth-challenged Hawkeyes.
The passing attack that many thought would blossom under Davis' leadership wasn't there.
Vandenberg went 21 of 33 for just 129 yards and was sacked six times.
