The perception that offensive ability and defensive ability are equal should be adressed. A player putting up points, especially in a tough context, like Burns last year (And this year, and the year before.), is worth a lot more than a player producing 20-30 less points with "safer" defense.
It stems from old beliefs that had the riskier european players take over the league with their offensive play and with less regards to the defensive side of the game. These would not have been allowed to be perceived as better than their canadian counterparts, thus, the defensive myth was born and it still persists to this day.
It got somewhat of a renaissance when the Habs had Subban, and the Sens had Karlsson. The eclosion of Karlsson as an offensive defenseman and the eclosion of Subban, as a lesser offensive defenseman lead people(Me included, I'm a huge homer.) to claim that Subban was better due to his defense, trumping the 20ish points difference between the two.
That's not true.
