The Cowboys also particularly struggled in the secondary this past season, ranking 110th out of 120 teams in the nation in passing defense (280 yards allowed per game).
Young, a former OSU outside linebacker/defensive end, was in his second stint on the Cowboy staff. He coached the offensive and defensive lines from 1976-78, before stops in the college ranks at Iowa State, Tulsa, Arizona State, Ohio State, OU, USC, Kansas and Miami. He also spent the 2001 season coaching the defensive line for the Detroit Lions.
Young was also the defensive line coach at OSU.
Young's departure leaves three voids on the Cowboy staff. Former offensive coordinator Todd Monken left OSU to become the head coach at Southern Miss, while inside receivers coach Doug Meacham will be hired as the offensive coordinator at Houston, a source confirmed to The Oklahoman on Saturday.
