The 2022-23 Pittsburgh Penguins have had about six games this season that could all be counted as their worst loss of the season.
That game where they lost a four-goal first period lead to the Detroit Red Wings.
Pretty much any of the games against the New York Islanders.
Losing to San Jose at home the night before the bye week and All-Star Game.
Getting absolutely embarrassed at home by the Edmonton Oilers.
Then on Tuesday night came the king of them, losing 6-4 to the Montreal Canadiens in a game that should have been perfectly set up for a win.
