Wyoming hopes veteran defensive coordinator can help slow No. 17 Fresno State and Derek Carr

After watching his defense give up more than 50 points in each of the last two games, Wyoming coach Dave Christensen knew a change was needed and quickly.

With No. 17 Fresno State bringing its high-scoring offense this Saturday night to Laramie, Christensen fired his defensive coordinator last week and hired veteran defensive coach Bill Young to help for the remainder of the season.

During a 44-year career, Young has coached defenses at a number of top programs, including USC, Ohio State and Oklahoma. He was last the defensive coordinator at Oklahoma State from 2009 to 2012.

Both the Cowboys (4-4, 2-2 Mountain West) and Fresno State (8-0, 5-0) feature high-scoring, spread offenses led by quarterbacks ranked among the top in the nation in total yards per game.
