Northwestern sophomore linebacker Anthony Walker has been named to the Associated Press All-American third team.
Walker led Northwestern's defense to new heights from his middle linebacker position in 2015. In Walker's first full year as a starter, the Wildcats ranked 11th nationally in total defense, 7th in scoring defense and 4th in S&P+, an advanced metric.
Walker had an outstanding individual season as well. The Miami, Fla. native finished tied for second in the country with 19.5 tackles for loss, and racked up 113 total tackles.
Walker was named a second team All-American by Sports Illustrated earlier this week. Last week, Walker was named to the All-Big Ten first team as well.
