Top-ranked Illini roll over Oregon, 83-66

? When Luther Head came off the floor after pregame warmups, he realized he’d forgotten to put his uniform jersey on.

It might have been No. 1 Illinois’ only lapse of the day.

Head had a season-high 23 points on 8-of-10 shooting, and all five starters reached double figures to lead Illinois to an 83-66 rout of Oregon (4-1) on Saturday at the United Center.

Deron Williams added 17 and seven assists, Dee Brown had 13 points and James Augustine had 10 points and eight rebounds. Roger Powell Jr. finished with 12 points despite spending most of the first half on the bench because of foul trouble.

“If you have any type of slippage whatsoever, they really make you pay,” Oregon coach Ernie Kent said.

This is the third time in school history Illinois (9-0) has been ranked No. 1, but it’s never been able to stay on top for more than a week. The Illini should break that streak now, winning all three of their games this week in convincing fashion.

No. 3 Georgia Tech 64, Air Force 42
