I admire BC for his effort, but it's nothing more than super novice armchair stuff.
First off let me say I totally agree with you . Let me see if I can explain this is a way you will like: I am performing a very informal method of attributing some "math" (counting) on the eye test. I have NEVER claimed it is "unbiased". I "attempt" to be as fair as possible, but realize that is "impossible" (human nature). That being said. My primary goal has been to attribute a + and - number to the general feeling towards a player. Obviously that "feeling" is completely subjective. But I have now attributed a numerical value to that "feeling".
Ways I could help make the scoring accurate:
Game measured this way by 100's of people: (Good luck, i have trouble getting a 2nd person to do this).
People have suggested I count more specific items: Trouble is, what does this accomplish? If we go to the right website, they already do this. Which leads me into the realm of advanced stats. Which I am NOT TRYING TO REPLACE with my measurement.
One positive to my scoring method is that it is all-encompassing. It includes passing ability, turnovers, defensive awareness, solid body play, offensive rushes, good shots on goal, basically everything you want to measure rolled into one stat. In this way the overall score should approximate the overall impressions of the player.
I am not trying to "compete" with "advanced analytics". But as with all math, there are issues with counting. And You appear to be an expert in the fact that numbers can be used inappropriately when they are poorly understood.
Advanced analytics are the definition of neutrality, dude. Honestly, I enjoy your work, and the effort you put in... but to claim you're unbiased is a lie. We are all biased, no shame in it. Thus, the system you set up is biased. The advanced analytics most commonly used eliminate much of the bias, light years ahead of the system that you use. Again, your system has value, just not as much. Not trying to hate, just sharing my opinion.
I feel I've addressed the bias issue above. Thank you for saying you appreciate what I am doing. I only do it to "add" to discussion.
This does open up for me the question of advanced stats. And why I am not just quoting Corsi/Fenwicks to explain the DRW Defensemen.
I understand these metrics. You have to realize EXACTLY what they measure to determine their usefulness. Corsi/Fenwick and shot metric stats are based around this general principal: Counting the shots directed at the net, doesn't matter if the shot misses, or is blocked, or whether or not the shot is a goal or save. Just shots. Count the shots.
This metric is supposed to go beyond scoring an IMPLY several things. If you are attempting more shots than your opponent, you probably have the puck more often, so you are controlling play (have more possession)
If you are attempting more shots than your opponent you should over time score more goals.
Thus this stat defines the style of play of the team and their chances of winning.
BUT what if you have a player who shoots / attempts to shoot EVERYTIME he touches the puck (Pulkkinen). He will score well in this category, assuming he isnt a complete black hole defensively. I find this metric for this type of player to be (inaccurate). Because my "eye" test can tell you that Pulkkinen misses the net more often than not. He also doesn't score much, has a low shooting %... etc etc. I think he is mostly ineffective. But Corsi/Fenwick measures him to be useful.
What about a player like Smith. Supposedly good with Shot metrics? (I actually dont the answer to this, which is why i asked OBEY to list our 8 D men)(If i wanted to do the research myself I wouldnt have bothered asking)(because i dont use these stats much, so i dont even know which websites to use). Well anyway according to the Hero Charts Dekeyser is bad at this, and Smith is great (Am I reading this right?).
But I know for a fact, by watching every game, that when Smith turns over the puck, it usually leads directly to a very dangerous scoring chance against. And Dekeyser not so much. Smith is much more of a liability by my eye test. So is Smith excelling in Corsi helping the team at all? I don't know. It doesn't "feel" like it. Someone show me some numbers to prove this.
The giveaway stats you posted state Smith / Green both have 18 giveaways. What counts as a giveaway. Flipping the puck out of the zone high in the air which turns over possession but not a scoring chance against = 1? And Smith turning the puck over leading to a 2on1 against = 1?
What I am saying is that these "neutral" "unbiased" "accurate" stats, when seperating the subjective outcome loses something. It loses the context of how "bad" or "good" that event was in the course of the game. My stats state Smith is making nearly double the number of mistakes vs ANY OTHER of our D men. This is a big number. Could i have miscounted his mistakes? Sure. Did I miscount by DOUBLE? (because I hate him?) NO. I don't hate the guy, and I seriously doubt I am counting 2x as many mistakes for him than for anyone else. This is why I have been posting my scores and time stamps so other people could check out what i have done. (of course no one does, so whatever).
I guess my point is: Corsi Fenwick does NOT take into account:
high quality scoring chances VS shots that have nearly NO chance of scoring. This is a problem if you are going to say 1 player is amazing and 1 is crap based on these "irrefutable numbers". IMO it is a flawed statistic. As are almost all statistics. BUT I appreciate what the statistic is implyingg. Dekeyser doesn't help our offense much, he doesnt help control possession or help us get shots on net. Smith apparently does this better, and helps us get shots on net. The fact Dekeyser blocks lots of shots in this metric is a negative. He shouldn't have "not had the puck" in order to block the shots in the first place. But he is stopping those possible shots from hitting the net.
I would like a more SUBJECTIVE stat.
Like Scoring chances for and against when Smith is on the ice. I feel this is a more direct measurement that implies his worth better than Corsi.
Scoring chances are hard to define though, so they are subjective. And prone to error in counting. But I like the conclussion from those stats more than simply shot differentials.
I understand that a team outshot by 10 shots a game is going to lose more often than not. But a player who shoots a lot, and is crap defensively will sneak through this stat and appear good when he is NOT.
So in a long winded way... What are the SIMPLE shot metrics on our 8 D men? What are the scoring chances for and against for them?
Oh one other thing. The video you posted, to me is an example of dekeyser doing the boring play off the boards and out turnover. I consider this play to be neutral. He isn't drastically hurting the team, but he sure as heck isn't helping it. He wouldnt score a minus by me on the play. But we both know, maybe another D man, in that position, could have done something else to score a + on the play. And Dekeyser just isn't going to be that guy. I think we overpaid Dekeyser a lot for what he brings. Do not think I am defending or promoting any of our D men under my scoring system, I am just counting plays in 3 categories (Good, Relatively Neutral, Bad). Turns out according to ME, Smith makes a lot of Bad plays. Also Dekeyser is kinda neutral (1 good play for each of his bad plays). And Ericsson has been making a lot more good plays than expected this year. And these measurements seem to go hand in hand with the general feeling on the board. Ericsson has not been the dumpster fire we expected.. thats good. Dekeyser has not done anything impressive... thats bad considering his salary.
