Jamie Benn, an instrumental figure in the Stars' team, was removed only a mere two minutes into the third game. This comes after his offense on Golden Knights' captain, Mark Stone, leading to a 5-minute major assessment and his removal.
It wouldn't be crazy to say that Benn may have just costed his team the series. Not only was Benn an instrumental part of his team, but he also allowed the Knights a 5 minute power play which gave them an easy goal.
