I think you're underrating assists here. Last year McDavid had 41g75a for 116p, Draisaitl had 50g55a for 105p but it's indisputable McDavid was the better player there. Those 9 goals don't make up the 11 points difference.If people want to say MacKinnon is better that's one thing. However if Matthews gets at least 55 goals that's hard to ignore no matter what his final point total would be.
Not to discount Matthews, he might have the best wrist shot since Sakic, but MacKinnon is clearly the better player.
