IU offense rolls again The nation’s No. 3 scoring offense entering Saturday broke the 40-point mark for the fifth time this season, piling up 529 yards of total offense with no turnovers. Rourke was 25-of-33 passing and enjoyed his third 300-yard performance in the last four games, while the Hoosiers averaged 4.9 yards per carry on the ground before the final drive.

Missed tackles plague Northwestern Indiana receiver Ke’Shawn Williams (5) breaks a tackle from Wildcats linebacker Xander Mueller for a 52-yard run in the third quarter on Oct. 5, 2024, at Martin Stadium in Evanston. (John J. Kim/Chicago Tribune) The Wildcats held Indiana to a turnover on downs and punt to open the game, but their defense gave up seven straight scoring drives — five touchdowns, two field goals — to essentially seal the game. The main culprit was missed tackling, namely on a 52-yard catch-and-run by Ke’Shawn Williams, who escaped four Northwestern defenders. Indiana’s 41 points were the most allowed by the Wildcats this season. The takeaway Indiana: The defense struggled to stop Northwestern at times, but the Hoosiers’ calling card has been the offense, which continued its dominant start to the season. Rourke excelled and was aided by a strong ground attack. Northwestern: Despite the loss, the Wildcats can find optimism in giving 6-0 Indiana one of its toughest challenges yet. Lausch rebounded well from a disastrous game at Washington, showcasing his abilities both through the air and on the ground. Up next Indiana: The Hoosiers are off before hosting Nebraska on Oct. 19. Northwestern: The Wildcats have a short week and will head to College Park to take on Maryland on Friday.
