"No Goal" — Stars vs. Sabres, Cup Final Game 6
1999In triple overtime of a Cup-clinching game, Brett Hull scored on Dominik Hašek with his skate clearly in the crease — a violation that, by the rule on the books that entire season, should have waved the goal off. The on-ice officials and the war room did not review it. Dallas was handed the Cup on the ice. They changed the rule the next year.
The league enforced the skate-in-crease rule hundreds of times that season, and then chose, in the single most consequential moment of the year, not to. Twenty-five years later the NHL has never produced a coherent explanation. Sabres fans never got one either.
