What happened: A community-made breakdown circulating on r/hockey identifies, for every NHL club, the trade partner it has gone the longest without doing a deal with. The creator pulled each team's most recent transaction against all other franchises, then surfaced the oldest of those pairings to show which clubs have effectively stopped trading with one another.

Why it matters: The exercise is a window into how front-office relationships and trade tendencies evolve over decades. Some pairings stay active through frequent swaps, while others go dormant for years as managers, philosophies and asset-matching change. It reframes familiar transaction history as a map of who does business with whom.

What to watch: Expect fans to debate the standout dormant pairings and dig into the trade histories behind them, with the creator likely to refine the methodology and wording as feedback rolls in.
