I’ve agreed with some of your comments, but I also feel some have went too far.
Evaluating him defensively only on his advanced stats isn’t a good strategy. I don’t like the idea of evaluating rookies on advanced stats. Rookies almost uniformly (even the best ones) are a product of their atmosphere. They have flaws, they don’t tilt the ice, they’re reactive, and they all make mistakes. I think you have to evaluate them differently.
And I think evaluating rookies is on a curve. You’re not expecting perfection. They’re on an ELC. They have a lot of potential growth. Maybe if your team is all in and you need immediate results you might harp on some of the faults, but I think generally you live with their mistakes and most people are very lenient when evaluating them. And that’s probably the way it should be. If they were evaluated like everyone else, very few would stick.
I don’t think it’s black and white. I think his defensive play is somewhere between great and terrible. And I don’t see the need to harp on his defending so often. Let the guy grow his game. It’s tedious when people harp on the faults constantly of the youngest regular defenseman in the league, especially when he’s generally having a very good season.
