Gurney: Cougar defense preparing for a different challenge this week against Utah

"Arizona presented a big challenge for the BYU defense, a challenge it largely met in keeping the Wildcats' high-octane offensive attack in check in helping secure last week's 18-16 win. While defensive coordinator Ilaisa Tuiaki was very pleased with the overall performance, he recognizes this week's opponent, Utah, brings a new challenge with its variety of formations."
