Wayne Gretzky spoke in a hoarse voice through a wide smile and even mustered a few laughs. The flu and laryngitis notwithstanding, the Hall of Famer's return to Madison Square Garden could not have been better. Illness, not anger, robbed Coach Gretzky of his voice. He didn't have to yell at his team Sunday night as the Phoenix Coyotes rolled to a 5-1 rout of the New York Rangers. Back in the building where he played the final game of his brilliant career eight years earlier, Gretzky stood behind the Coyotes' bench for the first time in New York and left with a most satisfying win. "I don't know if it was revenge," Gretzky said. "They're a good team. Over 82 games, you're going to have games where it doesn't go your way. We got a couple lucky bounces and did some good things, but I know the next game they play they'll be a much different team."
