Jalon Daniels threw for 280 yards and two touchdowns, and Devin Neal ran for 120 yards and another score, sending the Jayhawks past Illinois 34-23.
Daniel Hishaw added 98 yards rushing and a touchdown, and Lawrence Arnold had five catches for 89 yards, as Daniels and the Jayhawks (2-0) piled up nearly 300 yards of offense in the first half and finished with 543 for the game.
he Illini's Luke Altmyer threw for 202 yards and a touchdown while running for 70 and two more scores, and he showed some grit by bouncing back from a crushing blow from Kansas defensive lineman Austin Booker to lead a fourth-quarter rally.
The Illini (1-1) trailed 34-7 before Altmyer scored both of his TDs on the ground, and the 2-point conversions got them within 34-23 late in the fourth quarter. But the Illinois quarterback was picked off with 1:59 to go, ending the comeback bid.
