What happened: A reported deadline trade between the Toronto Maple Leafs and Montreal Canadiens involving Knies was scuttled by just one minute. The two sides had apparently reached an agreement but failed to finalize the paperwork before the deadline passed.

Why it matters: Missing the deadline means the Maple Leafs retain the player for their current postseason push, altering their roster construction. The incredibly tight margin of failure highlights the chaotic and unforgiving nature of the NHL trade deadline.

What to watch: Watch for how this missed transaction impacts both teams' offseason strategies and potential future negotiations.
