Mike Atkinson has often talked with his Boise State teammates about that rare moment of glory for a nose tackle: The elusive pick six. That heroic moment finally came Thursday night when he dropped back into pass coverage, stepped in front of a throw by Brigham Young quarterback Riley Nelson and rumbled 36 yards for a touchdown. His score turned out to be the difference as the No. 24 Broncos (2-1) held off a late rally to beat the Cougars 7-6 in a game dominated by defenses and marred by turnovers and penalties.
