A look at line and pairing success rates through 28 games

forex handel wiki The Rangers are currently on a one-week break, so this is a good time to take a step back and assess which lines and pairings have been effective, and which have not. Given the large number of injuries, specifically to the forwards, only five lines and nine forwards have logged enough ice time together to make the charts (courtesy of Sean Tierney).

iota singer While the lines are most certainly not complete due to injuries, it’s clear the Rangers have one line that is a cut above the rest, and that is the Chris Kreider-Kevin Hayes-Filip Chytil line. That line has been spending a lot of time together lately, and they are just flat out good. On the opposite end of the spectrum is the Jimmy Vesey-Brett Howden-Ryan Strome connection, which has been relatively atrocious. The rest are neither here nor there, but it’s worth noting that Kreider with Mika Zibanejad and Jesper Fast seems to trade chances.

minocycline antibiotic 625mg This passes the sniff test, since the Kreider-Hayes-Chytil line has been visibly the best line out there recently. We also enjoyed watching the Kreider-Zibanejad-Fast line when they were together, hence the lower right “fun” section. The injuries to Pavel Buchnevich and Mats Zuccarello have altered what lines we see here. When they come back, I’m intrigued to see what sticks.

clozaril zyprexa 5mg While injuries have decimated the forwards, the blue line has been healthy. The best thing we can say is that the Fredrik Claesson-Kevin Shattenkirk pairing is, at the very least, good defensively. I guess we can say it’s good that no single pairing is in the “bad” section. But there are none in the “good” section either. This is just a mess of mediocrity. On the bright side, they can’t get any worse…probably.

benicar price at cvs Despite that 9-1-1 run in November –which was fun while it lasted– the Rangers are what they are. We expected them to be mediocre, leaning towards bad. So far the numbers are showing exactly that. The production has been mediocre to bad, with some flashes of good. Sometimes stories aren’t exciting, and the predictions are somewhat accurate.

That said, they aren’t a playoff team. As the Rangers sell off more assets, it’s expected that these numbers and results will only get worse. Rebuilds are great on paper, but these are the tough times that were expected.

    how much does motrin 800 cost without insurance I really don’t get people’s commitment to the expected goals stat, or see why it’s “better” than Corsi. One thing that has made me dislike XG% is that it’s a hypothetical statistic. It justifies good efforts in losses with a nebulous “oh, they should’ve won”, which to me is a fairly baseless stat. In a league with as much parity as the NHL it’s arguable to say that every team has a relatively equal chance to win a game.

    http://envoguemusic.com/buy-Zyloprim-online.html A sport like hockey that has so much randomness (deflections, bad bounces, bad ice in certain arenas etc) built into its everyday play can’t truly be quantified at some levels, and XG seems to be a stat that is attempting to do just that. Can’t understand why so many people are enamored with this stat, to me it should be called the “should’ve/could’ve but didn’t” stat, as it justifies performance with on-ice events that don’t actually occur. And since it is a statistic I’d think that by definition it has to deal with real past-time events; anything that justifies probability is quantum physics, and not really a sports statistic.

    tadalafil 20mg dapoxetine 60mg Feel free to have at it; I’d like to hear from defenders of this stat, and find out why expected goals are something more than the latest flashy new fancy stat.

      antivert price First of all, I question how these really detailed stats can be accurately tracked for every player on the ice, every shift, with players all over the place? Who is tracking it? Seems like an impossibility to me.

      http://kurtlarlakosankadin.com/buy-zanaflex-no-prescription.html But anyway, the idea I guess is that everything eventually falls to the mean and “unlucky” play is corrected down the road, if the overall trend is on an upward trajectory.

Shatty is a fine 2nd pair complement or top pair D man if there is a strong partner. Claesson has been their best D man which in itself tells you the state of the D corps.).

        ic propranolol 10 mg Each arena has a team of people that track player location data for shots/goals/hits/etc. There are 5 individuals watching the game and recording these events, with a manager to ensure quality (to the best of their ability): https://www.nhl.com/kings/news/the-art-of-keeping-stats/c-708365

        epilepsie keppra 1000mg filmtabletten Furthermore, stats websites such as Corsica and NaturalStatTrick all offer “adjusted” metrics of the raw numbers. This means arena bias is adjusted towards league average based on historical weights of how the NHL employees tend to track. For example, MSG is notoriously biased to record shots closer to the goal than they actually happened. So anytime I write my stats-based articles, I’m using adjusted data for the league in order to remove some of that bias.

          source url Isn’t the concept of “adjusted” data something that contaminates the data itself? To pull out another quantum mechanics idea here, the act of observing an experiment or event influences the outcome of any experiment or event. If the raw data is being manipulated after it’s been compiled, then it’s not really an accurate picture—it’s more of a probable picture. That’s a pretty significant difference, and it makes the fancy stats crowd look like they’re exaggerating the correlative accuracy of their metrics in terms of the reality of any individual hockey game.

            http://nc4psouthafrica.com/cheap-trileptal-for.html No, it’s just weighted averaging that improves the correlation to goals for % based on the large sample size of now 10+ seasons of shot location data. And it’s not just improving the data to look good – there are arenas where the bias tends to record shots from too far away, so the net effect is positive in that case. All in all, the sample size is large enough about 1/3’rd of the way to the season to start washing out the noise to become statistically significant. This is done across the board in all major sports with these statistics.

And that goes for stats, mathematics, or science. Just because there’s an agreed-upon bias applied to the data by a large number of analysts, it doesn’t make the data more legitimate. In my eyes it’s less legitimate, because it’s being shaped by outside conditions being imposed upon it by analysts.

                follow I don’t think that’s an appropriate comparison. Weighting assignments doesn’t imply messing with data, it implies that some events are more important than others, which would imply that a statistical measurement like this is a probability-based one. That’s what I’m arguing here—XG% is pretty subjective, especially if the original data set is nudged in one direction or another.

        see One can track all of this, although there is occasional sloppiness. Player A makes a bad line change and his replacement is charged with being on the ice when the bad thing happens. But there are problems with everything. There is no proof AFAIK that it is legitimate to assign stats to individuals.

        Regression to the mean poses a major problem. Some characteristics can be measured more accurately than others. The implication (true) is that the less reliable stats will regress more than the less reliable ones. However, what this necessary undervaluing of the less reliable stats leads to is the undervaluing of the strengths measured by these stats.

        For a shooter, for example, both quantity of shots and % success matter. But because we can measure quantity more accurately, we overvalue the prolific weak shooter over the more accurate one who takes fewer shots.

        Skjei possession stats are below his career norm, and he is predominantly in on d-zone starts which may help explain it. His skating and puck handling are good, he has size, his confidence IS NOT GOOD,IMO, he still has upside, I think. He’s far from a bust, I think he’ll snap out of it.

        You just described a lot of teams. We aren’t that bad, we aren’t as of yet that good. We have some TOP top top quality coming down the pike in the next year or two (Miller and Kravtsov) and our D’ isn’t quite as bad as you suggest (I mean have you even watched ADA play?). Stay the course and move a couple of forwards (Zucc and Names) and one or two of Smith, Staal and McQuaid — although I think Staal is staying.

      A lot to unpack, so I’ll try to keep it concise:
      1) Expected goals are only a “hypothetical statistic” in the fact that an expected goal event rarely equals 1, otherwise known as an absolute chance at a goal. This makes intuitive sense, because even if you’ve deke’d the goalie and have a wide open net, things can still go wrong and have gone wrong in the past from that location on the ice. The Evolving-Wild twins do a cool thing every week on Twitter where they take the highest xG events of the week and put video to them. If you watch the videos, you’ll get a sense that basically the higher danger the chance is, the higher the xG is, which is the whole idea of expected goals: https://twitter.com/EvolvingHockey/status/1069451264558280705

      2) Randomness is taken into account in expected goal models, as shot types are classified by the NHL. To your point, rebounds and deflections often have higher xG counts because they’re very hard to stop. Also, every location in the zone has a historical shot %, so that is applied as well.

      3) Just a thought to your “should’ve/would’ve” analysis: you’re right to an extent. If the Rangers win the xG battle 3-2 but lose the game 2-3, it is fair to say (to an extent) that they should’ve won the game and luck/randomness had not gotten in the way, they would’ve. That being said, the reason Corsi and Expected Goals are used in this manner is because over the course of 82 games and the playoffs the actual goal outputs regress towards both the shot share and expected goal outputs (regression can be positive or negative, of course). A recent example of this is the Sabres, wherein during their 10 game win streak they had an expected goals % of 44.8 (all situations), aka not good. A big part of why they ended up winning those games, though, is that they shot 9% (above average) and got 0.925 save% goaltending (top 10 level). Since then, they’ve lost 4 straight, with an xGF% of 38.7, a save % of 0.929, but a shot % of only 8. It doesn’t seem like a major drop, but the 1% in shooting puts them closer to 2 goals a game rather than 3, which ends up in more losses than wins.

        Thanks for the thorough explanation, Rob. Much appreciated. I still ultimately disagree with most folks on the inherent value of the XG stats.

        To me, this stat is like many fancy stats in that it’s offered up as set-in-stone statistical evidence by many writers and fans, when it is something that should be viewed as a probability metric only. And as such, I don’t see its value as much as Corsi/Fenwick and the other first-generation fancy stats. To each their own though I guess.

        Suppose you have a 2 on 1 break. Is there really anything in xGA or xGF that takes into account how good the three players involved are? A good defenseman tries to give his goalie a predictable shot, but what is the difference between a predictable shot and one the goalie cannot anticipate.

          To my knowledge no NHL Expected Goals model takes into account which players are involved, and while this of course matters in hindsight as to whether the puck went in or not, it would negatively influence the purpose of the model. Regardless of who is shooting the puck for the scoring chance, the expected goal level is based on all of the history of that location of the chance – both good and bad (meaning good and bad players). Over time, better players accumulate more expected goals for because they continuously get more quantity and quality scoring chances.

          The difference between a predictable shot and one the goalie cannot anticipate is the nature of the game, or put another way, randomness and luck.

            “The difference between a predictable shot and one the goalie cannot anticipate is the nature of the game, or put another way, randomness and luck.”

            You could not be more wrong. Two on ones are easy to understand, but all hockey is like this to a certain extent. The defenseman is basically helpless to prevent a shot. Playing perfectly though, he thwarts the pass so the goalie knows who will shoot. He also hinders the shot a little so that the goalie has a better chance. And this is about skill.

            So here is the problem with xGA. A two on one will be assessed the same way whether Vlasic or Yandle is defending (a superficially great shot will happen). The xGA charged to Yandle and to Vlasic will be the same. So this play at least tells us that Yandle and Vlasic are equal. And yet, it is not an accident that the puck ends up in the back of the net when Yandle is defending and doesn’t when Vlasic is.

            Another point is that while a breakaway is a breakaway, a good defender is far more concerned about allowing a Crosby breakaway than a Tanner Glass breakaway. More generally, one might allow a really good shot to an Oveckin teammate rather than a good shot to Ovechkin.

            **********

            All of these stats are predictive, but they are also defective. What you are saying is that everything you can’t measure is luck. Yes, there absolutely is luck in hockey. The third goal in Philadelphia scored on hank would have been prevented by most goalies and by Hank on most days. The rebound bounced into a defender and into the net. Nine times out of ten the rebound goes somewhere else. However, the expected outcome of an opportunity depends on many things that are tough to measure. By design, some players are “lucky” and some are not.

            xGF, xGA are attempts to remedy the weaknesses of Corsi and I do not know how good they are, though I know they are not as good as their adherents think. However, I will give a thorough explanation of the weakness in Corsi – if you are willing to listen (read).

            Goal scoring depends on Corsi and PDO. My analysis says 70% PDO, 30% Corsi; I know of no one else who has looked at it. A hockey game produces ten times the Corsi data as PDO data and so it seems reasonable to believe that we can determine statistically how good a player is Corsi-wise, but even say 20 games gives incredibly unreliable PDO numbers. If you simply want to predict which teams will win, relying on Corsi tells you something because it is real while the PDO numbers seem worthless. HOWEVER, it is a fact that there are good PDO players and bad PDO players. The greats excel in both categories. However, there are good Corsi bad PDO guys and bad Corsi good PDO guys. Choosing between them depends on how good is good and how bad is bad. BUT fancy stats will tell you that the good Corsi guy is better when in fact, all things being equal, the reverse is the case.

            AND COACHES CAN SPOT POOR PDO PLAY!

    I think we need to break out offensive side and defensive side of the pairs. We just do not have great defensive players. There is also the “stupidity factor” which shows up on no chart. It it when a defenseman makes a bonehead play (see Skjei on the penalty call) or takes a bad penalty (Smith many times). These tend to all to turning points of the game.

    Actually, my reading of the charts are that the Staal-Pionk pair has been pretty good. Yes, they are only average defensively and a tad below average offensively, but they are the guys opposing Ovechkin, McKinnon, McDavid, et al. Going up against the big boys and coming pretty close to holding their own. Unfortunately, I presume these are all 5 v 5 numbers and they have struggled on the PK.

    The other defensive pairs have gotten much easier assignments.

    Hockey has five skaters on the ice, all of whom have roles in what happens offensively and defensively. Separating out defensive pairings from the forward lines that are on the ice with them as if the defensemen are the only players responsible for goals against for example seems to me to be intrinsically invalid. Furthermore, after 28 games, you are still talking about a small sample size. You also don’t capture the quality of the opponent.

    I am not sure that one can put too much stock in the stats and draw firm conclusions from them. Unfortunately, articles that use them usually present the results without what I consider to be necessary caveats.

    I read the graph and see that Fast could turn a positive group into some sort of negative unless he plays with Howden and Vessy. Though Howden, Vessey and Strome looks like they play better together though the stats don’t demonstrate that. I don’t think they have enough time on ice together to make a call.
