In a rocking new arena, with a fan base suddenly alive, Nebraska basketball has a good thing going these days.

Forget the Cornhuskers’ overall record, which stands at 13-10 after a 67-58 victory Wednesday against struggling Illinois. They’re 11-1 at Pinnacle Bank Arena — really a heck of a place — and have a genuine star-in-the-making in 6-6 guard Terran Petteway, who entered the game leading all Big Ten newcomers in scoring at 17.5 points per game.

Petteway scored 16 points for Nebraska before fouling out late, but the surprising show-stealer was sophomore forward Shavon Shields, who exploded for a career-high 33 points. That’s some kind of one-two punch.

By comparison, it raised a serious issue about the Illini (14-11, 3-9 Big Ten), who have lost nine of their last 10 games. And the ­issue is the Illini wouldn’t know a one-two punch of their own if it punched them in the face.

Rayvonte Rice had another strong night, scoring 23 points and adding six rebounds and three steals, but no one else had a standout game — at least not offensively. Freshman Kendrick Nunn was the Illini’s second-leading scorer with nine points.

Without a consistent No. 2 scoring option — and it’s clear Illinois just plain doesn’t have one — it’s going to be extremely difficult to get any sort of a season-saving winning streak going.
