Nebraska fans don't have to look any further back than Friday to know what kind of havoc a long, rangy defensive line can stir up.
Iowa rolled out a series of 6-foot-6 or taller players like A.J. Epenesa, Anthony Nelson, Parker Hesse and on down the line that were able to get hands on the NU offensive linemen — and most others they faced this season — and either control a gap or get into the backfield.
The Huskers have some guys coming back for 2019 that can be disruptive — Carlos and Khalil Davis, for example — but coach Scott Frost has been realistic through his first year about the kinds of body types that NU has up front.
