 Wayne Gretzky's first Stanley Cup appearance, he lost to the New York Islanders. He went on to win four of the next five championships. Sidney Crosby lost his first Cup appearance to Detroit in 08, came back and won it in 09, also against Detroit. So sometimes, no matter how great you are, you still have to lose in order to win. You've got to learn that. And this is certainly going to be another learning curve for McDavid and Crosby.
