No. 18 Nebraska expecting to know a lot more about its defense after facing Smith-led Wyoming

Nebraska coach Bo Pelini expects Wyoming's spread offense to offer a good test for the 18th-ranked Cornhuskers' young defense on Saturday night.

Wyoming third-year starting quarterback Brett Smith is one of the nation's top returning passers. He averaged 308 yards in total offense and threw 27 touchdown passes against six interceptions last season.

Two years ago, Smith threw for 166 yards and two touchdowns in a 38-14 loss to ninth-ranked Nebraska in Laramie, Wyo.

The Huskers' biggest question marks are on the line and at linebacker. Coaches plan to rotate players in and out.
