By the fourth quarter, the Hawkeyes had seemed to crush the Buckeyes' spirits.
That stunt led to perhaps Stanley's best play of the day, an under-duress touchdown pass that gave the Hawkeyes a three-score lead late in the third quarter.
J.T. Barrett threw a career-high four interceptions for Ohio State (7-2, 5-1, No. 6 CFP), which allowed its most points in a game under coach Urban Meyer.
However, on Saturday evening, the Buckeyes headed to Iowa City and found out why Kinnick Stadium is a death trap for highly ranked teams.
Iowa: Where in the world did this come from, Iowa?
Iowa has played back-to-back 17-10 games, first losing at Northwestern, and then beating Minnesota last week.

Say goodbye to Ohio State. Iowa - a team had scored 27 points in its past two games - completely decimated Ohio State in every way.
The visit to Iowa began on an extra-ominous note for Ohio State and Barrett. The Buckeyes return home to host the Michigan State Spartans, who upset Penn State on Saturday. The Hawkeyes broke out alternate blackout uniforms for the occasion, delivering a potentially critical blow to the College Football Playoff hopes of the Buckeyes.
There will be no time to rest for the Hawkeyes, who travel to Camp Randall to take on the Wisconsin Badgers next Saturday.
