What happened: An Athletic article details NHL Rule 4.1: if officials fail to appear and no replacement agreement, home team picks referee, visitor linesman from their skaters. It happened once in 1983 Hartford Whalers-New Jersey Devils game, with Garry Howatt and Mickey Volcan officiating. Many GMs unaware; polled on hypothetical picks.

Why it matters: Highlights NHL's quirky preparedness for rarities, unknown to insiders like Colin Campbell. Adds fun history amid late-season officiating scrutiny but no current impacts on standings or bets. Ensures continuity in unforeseen scenarios.

What to watch: Monitor referee availability and controversies heading into playoffs.
