The stats are the results; you're arguing the minutiae. He allows less goals, relative to his teammates, than almost every single defenseman in the NHL with similar usage over the last three years: those are the results. What you're saying is that Gardiner, despite his results, is not a good defenseman (defensively), because when you watch him he doesn't look effective.
No one has ever said that Gardiner is 'good at everything'. He's not a good special teams player, and therefore not a true top-pairing defenseman at this point.
But yeah, keep building those straw men.
The issue is that you
only see the mistakes, and fail to acknowledge the great (of which there are many) plays.
All of these statistics are even-strength statistics and... oh, would you look at that, Gardiner has lead the Leafs in even-strength ice-time in each of the last two seasons!
You wrote that he "creates offensive chances for the other team by his lack of awareness".
Despite this "lack of awareness", he allows less chances than everyone else on the team, so if Gardiner "lacks awareness", then everyone else on the team must be entirely bereft of it.
I said over a short-sample-size it's luck, and it is. Over a large sample size (years of data), it isn't. Crosby, for example, has an on-iceSH%RelTM and PDO consistently above baseline. That's because (at least in part) Crosby averages four-times the league average in passes to the slot.
It's just a fact: players have a higher SH% in the slot. Which, of course, makes perfect sense.
Gardiner has a career on-iceSH%RelTM of -0.7, while his on-iceSH%RelTM last season was -2.1; his career PDO is 100.5, and was 98.2 last season; his career on-iceSV%RelTM is 0.9, last season it was 0.4.
So yes, Gardiner was very unlucky last season.
No, I say it's skill when it is skill, and luck when it is luck.
He has a career GFRelTM of 2.0. I've never argued that he's been productive offensively: he hasn't. What I am arguing is that, aggregately, he's a good defenseman, and defensively he's very good. Perhaps he's not good defensively in the traditional sense (hit people, block shots, allow tons of goals against), but in terms of preventing goals, scoring chances and shots (things that actually matter), he's been very good throughout his career.
They're not the perfect analysis, and no one has argued that they are. All I'm arguing is that they're much more reliable than the eye-test, because they are.
It depends what they're trying to define. They measure pretty much measure everything: successful pass attempts in all three zones, pass attempts to particular areas within the zones, loose-puck recoveries, without puck plays, with puck plays, defensive-zone success rates, offensive-zone success rates, slot passes, o-zone touches etc.
I think there are three categories they use predominantly: LPR (loose-puck recoveries), PDP (possession driving plays) and successful d-zone plays (without the puck). There's more subcategories, but I think those are the big three that they classify plays into to start, and then work to further pinpoint their classifications (I could be wrong though).
Currently, sure, but that's only because they haven't released most of the information/data they have collected.
I'm not sure. They've released a couple Leafs articles, but they focused on Rielly and Gardiner being fantastic at zone-exits (which we all know, I think), and Phaneuf being poor defensively and having a really bad contract (which I think most people know).
