Two top 10 teams battle Saturday, as the No. 7 Nebraska Cornhuskers travel to the Pacific Northwest to face the No. 2 Washington Huskies (ABC 3:30 EDT). The key to this game is power: Nebraska's running game against Washington's eight-man defensive front.

Diagram #1: A traditional defensive set has seven players in the box: four defensive lineman and three linebackers. Against Nebraska's I-Formation, this alignment favors the offense -- seven blockers on seven defenders. Teams that try this against the Huskers get run over.

Diagram #2: Within Washington's defensive scheme, the strong safety, Nigel Burton (#8) comes into the box, while the free safety Tony Parrish (#7) plays center field. Bringing the strong safety into box gives the Huskies the advantage against the run -- seven blockers against eight defenders.
