Illinois (6-0) jumped to a 13-3 lead, and a 17-4 run at the end of the first half pushed the Illini’s advantage to 44-19 at the break.
Henry, a freshman forward, returned from an ankle injury and came off the bench on Sunday. After close wins against Richmond and Illinois State in which coach Bruce Weber had to rely on a small rotation of veteran players, the large leads throughout Sunday’s game allowed Weber to dip deep into his bench.
Five Illini players finished in double figures, with the bench contributing 48 points.
Chicago State (0-6) was led by forward Jeremy Robinson’s 14 points and six rebounds in its lowest scoring effort of the season.
