With several teams in the Top 25 on a bye and very few ranked matchups on the slate, Week 7 of college football looked like it might be a return to normalcy after a wild Week 6. The Purdue Boilermakers decided against that.
In one of the major upsets of the 2021 season, the Boilermakers marched into Iowa City as a double-digit underdog and left with a 24-7 statement victory over the No. 2 Iowa Hawkeyes. The Purdue offense wouldn't let the Iowa defense off the field, and when the lead stretched to 17 points in the fourth quarter, it felt as though the Hawkeyes didn't have a path back into the game.
