NHL Awards are not typically won in the first month of the season -- but there are always exceptions.
Look at the NHL Awards Watch from one year ago. Quinn Hughes ended up winning the Norris Trophy and Connor Bedard was the eventual Calder Trophy winner. But 2023-24 award winners like Nathan MacKinnon (Hart) and Connor Hellebuyck (Vezina) weren't really on the radar with voters quite yet, something that changed rather quickly as the season carried on.
Some of the current leaders will no doubt still be leading at the end of the season, while others are just getting their moment in the spotlight before fading from the finalists' picture.
