LINCOLN — Finally. It was Nebraska's turn for some late-game heroics. The Huskers stunned undefeated Michigan State and snapped the Spartans' 12-game winning streak Saturday night with an improbable game-winning drive — covering 91 yards in 38 seconds — to earn a 39-38 victory. NU got the ball back without any timeouts trailing by five. And quarterback Tommy Armstrong went to work. He found Jordan Westerkamp for gains of 28 and 33 yards on back-to-back plays.
