Penn State pulled off some huge comebacks in 2016. But nothing quite like this. The Nittany Lions surrendered the lead to Iowa with 1:42 left on Saturday night but marched all the way down the field for a 7-yard touchdown from Trace McSorley to Juwan Johnson on the final play to beat the Hawkeyes 21-19. Akrum Wadley’s late 35-yard touchdown run appeared to give Iowa yet another stunning upset.
