Top-ranked Iowa, the prohibitive favorite to repeat as champion, was second with 22 points and eight wrestlers alive in the championship bracket. Ohio State was third with 17.5 points and Boise State and Nebraska were tied for fourth at 15.
Iowa State is the only school to qualify a wrestler in every class.
