Linebacker Anthony Walker was a big reason why Northwestern ranked sixth in the nation in defensive efficiency in 2015.
The 225-pound sophomore was named first-team all-Big Ten Monday by both the coaches and the media.
Walker led the Wildcats with 113 tackles, including 19.5 tackles for loss and three sacks. He also added a sack, a forced fumble and three fumble recoveries, including one for a touchdown.
He was the only Northwestern played named to the defensive first team. Seniors Dean Lowry and Nick VanHoose each made the second team, and senior defensive end Deonte Gibson, junior defensive back Matthew Harris and sophomore kick returner Solomon Vault made the third team.
The offensive team will be revealed Tuesday.
