Iowa is trailing Colorado State at the half after a stunning first 30 minutes at Kinnick Stadium on Saturday afternoon.

The Hawkeyes were favored by more than three touchdowns vs. the Rams, but struggled to move the ball before the break. The result? A 14-7 halftime deficit.

Colorado State had advantageous field position for both of its scores. The first came after Iowa’s offense went 3-and-out near its own end zone and the ensuing punt made it to just the 35-yard line. The Rams’ second score came on the heels of a 56-yard interception return.

Iowa fans are blaming the performance on offensive coordinator Brian Ferentz. The Hawkeyes gained 179 total yards in the first half, but 92 of those yards came on just two plays.

The Hawkeyes went just 2-of-5 on third down, which is a major difference in the game so far. Colorado State went 9-of-13 on third down in the first half.

Spencer Petras finished the half 7-of-10 for 11 yards, 1 touchdown and 1 interception. Running back Tyler Goodson carried the ball 8 times for 41 yards.

Here’s some of the reaction to Ferentz’s offense in the first half:
