BYU spoils Sumlin's debut with 28-23 win over Arizona

TUCSON, Ariz. -- Brigham Young's offensive line pushed Arizona around. Tanner Mangum was effective in his return from an Achilles' tendon injury. The Cougars kept Khalil Tate from breaking off any big runs. BYU expected to be better after a four-win season ago and sure seems to be after opening the season with a road win over a Pac-12 team. Squally Canada scored on three short runs and BYU spoiled Kevin Sumlin's Arizona coaching debut with a 28-23 win over the Wildcats on Saturday night. "We've been thinking about this for a long time, so really happy for the team in their ability to get the win," BYU coach Kalani Sitake said. BYU went 4-9 last year, but was overpowering up front on offense and the defense limited Tate's effectiveness by not letting him get out and run.
