ANN ARBOR, Mich. -- Devin Gardner trotted onto the Michigan Stadium turf with 18 seconds left, Michigan trailing by three points and, for the quarterback making his second career start, one more question of his capability rising up. Consider it answered. Any questions about Gardner's ability to play quarterback passed with one final throw, one last drive. Gardner scrambled around and saw Roy Roundtree open. He threw it up, an on-target heave 53 yards in the air.
