Nebraska rush offense vs. Illinois rush defense
Nebraska is getting good production from I-back Ameer Abdullah, who has rushed for at least 98 yards in all four games so far and ranks third in the Big Ten at 116.2 per contest. NU also will hit the Illini with an offensive line that is playing well and depth in the backfield. Illinois failed its biggest challenge against Washington, when Huskies tailback Bishop Sankey ran for 208 yards and a TD. Edge: NU
Nebraska pass offense vs. Illinois pass defense
Husker quarterbacks have been efficient so far, completing 70.3 percent of their passes with 11 TDs and just one interception. Redshirt freshman Tommy Armstrong isn't as polished as Taylor Martinez, but he and Ron Kellogg are surrounded by good targets. Illinois' first three opponents passed for 300-plus yards before Miami only attempted 15 throws against the Illini. Edge: NU
Illinois rush offense vs. Nebraska rush defense
Illinois has to be licking its chops after South Dakota State tailbacks gouged the Husker defense for 8.8 yards per carry and were never tackled for a loss. The Illini have averaged only 37 attempts a game, so the emphasis will be on getting the most out of those runs and keeping the NU defense honest. Edge: Illinois
Illinois pass offense vs. Nebraska pass defense
Illinois senior Nathan Scheelhaase has been a pleasant surprise in his transition from dual-threat quarterback to a pro-style offense. He ranks No. 10 nationally in passer efficiency and leads the Big Ten with 290.5 yards per game. Nebraska will have to find a way to generate some pressure, but also remember that he can be a dangerous runner if allowed to escape the pocket. Edge: Illinois
Illinois has edges in both kickoff and punt return numbers, although Kenny Bell appears to be closer and closer to breaking some kick returns for Nebraska. The Huskers lead all Big Ten teams with 20 touchbacks on kickoffs and rank third in net punting (39.7 yards). Illinois already has missed three field goals. Edge: NU
Both teams have struggled defensively, but Nebraska has forced 10 turnovers compared to just four for the Illini. NU also is coming off a bye, and is 4-0 over the last four seasons in games after a week off. Illinois is leaving its home state for the first time after three games in Champaign and one in Chicago, and the Illini won just four "true" road games since 2008. Edge: NU
Key matchup: NU safeties vs. Illinois' deep pass
It might be a big Saturday for Corey Cooper and the Nebraska safeties with Illinois' propensity for throwing the football down the field (22 pass plays of 20-plus yards). It also could be a welcome change from the first four opponents completing 63 percent of their passes with a variety of shorter throws mixed in. The issue for the Huskers is that their safety play hasn't been great, and it's unclear who will take most of the snaps next to Cooper.
Nebraska wins if ...
Its defense can force some turnovers and avoid the huge play.
Illinois wins if ...
It can give Tommy Armstrong a rude welcome to Big Ten football.
Illinois already has scored 161 points, more than any previous Illini team ever put up in the first four games of a season. Nebraska is averaging 43.2 per game despite a scoreless second half against UCLA and a let-up against Wyoming. So the bottom line might be which of the porous defenses (NU ranked No. 107, Illinois at No. 92) can piece together a few stops — or which offense can score last. If the conditions are at all a factor, the Huskers have an ace in the hole with their running game.
Our prediction: Nebraska 40, Illinois 35
