Let's get this out of the way: Brad Treliving is a very good general manager.
He couldn't have handled this offseason's goaltending reboot any more perfectly. He acquired Dougie Hamilton for nothing more than a handful of picks and seemingly restocked the Flames' defensive cupboards overnight. He's executed both trade deadlines he's been in charge of perfectly, and he pulled the trigger on changing coaches at the right time.
But Treliving is not a perfect general manager. His first few months on the job weren't great. Specifically, he either acquired or handed out a lot of money before his team even played a single game under him.
