Will another defenseman win the art ross?

[Beukeboom]

His best season he was 24 points behind, not sure how much more puck luck he could get.

As for the OP - not a chance. Orr was literally a once in a lifetime player, even for those who weren't alive during his playing career.

But taking out the Kane anomaly he was just 7 points from Benn. Still not very likely of course.
