Why The Los Angeles Kings Missed the Playoffs: An Open Email

I’ve been asked by a couple of people how a team with a normal PDO and strong metrics could have missed the playoffs entirely. It’s an important question to address, particularly because the playoffs are so much more important than worrying about whether you’re lucky enough to win the Stanley Cup. I composed an email response, and felt good enough about it to open it up. While this doesn’t comprise the whole of the explanation (certainly, there’s some “blame” that goes to Calgary & Winnipeg), they’re points that I’m not seeing made elsewhere.

Hi XXXXX,

A couple of things really hurt the Kings. One is a cruel fact of a low-scoring league: if more games are going to be decided by one or two goals, it increases the likelihood that a fluky goal can impact a team in the standings. The Kings had the most overtime losses in the Western Conference; last year they were tied for the second least in the West. The second thing is the tank battle…the West had two teams with historically bad records – add in games against Buffalo, and we have three teams that will end the season with point totals that were typically reserved for the sole worst team in the league in other seasons. On the flip side, that creates a rising tide for all the other ships in the league, and raises the bar for getting into the playoffs. I mean, needing to get nearly 100 points to get in? Last year, the bottom team in the West, Dallas, had 91 points. A nearly identical record to this year got Los Angeles into the playoffs in the 8th seed in 2011-12.

Maybe the closest comparable circumstance was 2010-11, when the West again had two sad-sack teams (Colorado, Edmonton), and the East was noticeably weaker than the West. It took Chicago 97 points to get in. Also, look at 2006-07…Colorado didn’t make it with 95 points, having gone 44-31-7 during the season. If the West is considerably stronger than the East, as it was back then, you could also end up with a tougher path to making the playoffs. In ’06-07, every team in the Western Conference, save the 8th seed (Calgary, with 96 points), had 104 points or more!

Anyway, this year’s league created a scenario where a good team, by any measure, might not get in. The Kings went 39-27-15, outscored their opponents by 12 goals (in fact, they tied for 2nd in the league in goal differential at even strength), and could get 95 points and not make the playoffs. In the loser point era, there were only two seasons that was even possible, and both occurred in the stronger Western Conference. It’s a successful season by anything except the fluid marker of the playoffs, which unfortunately for them is all-important to reach.

Hope this helps,

Best,

Ben

Note: One critique I’d like to address – yes, all teams in the league are theoretically dealing with the tank battle, but tanking doesn’t occur across the entire season, which means that teams that have already played most or all of their games against tanking teams earlier in the year won’t have the benefit. Additionally, those same teams might have the resulting, added pressure of a more-difficult set of opponents through the latter portion of the season. If the difference between making the playoffs versus not is a matter of a few points, the difference in scheduling can become all the difference in the world.

Who are NHL Coaches Playing More with the (Big) Lead?

Right out the gates, I knew two things: 1) I wanted to take TOI% data from close scores and subtract it from TOI% data from 2+ goal leads, and 2) that it would automatically tell us that perceived poorer players are given more playing time with the lead. Why? Because they tend to play less when the score is close, which increases the likelihood that a differential with 2+ goal time on-ice will show they get to play more with a big lead. That said, I wanted to run a quick study to see just how much of a difference that time swing could be, and which players come out of the woodwork on either end.

But first, I want to whittle away the small sample players, and to do that I’m going to run a quick test to see at what # of games played this TOI 2+ minus TOI Close differential (let’s call it “TOI Lead Diff”) stabilizes.

Hockey Talk: On player control over save percentage

Welcome back to our semi-regular segment where I will touch on a few trending topics in hockey statistics in a less mathematical and more discussion-based format.

This week we will explore the debate on player defensive impact on shot quality and save percentage.

So let’s begin.

The Greatest Tank Battle: Penguins vs. Devils, 1983-84

What do you do when a 6’4″ QMJHL forward who scored 184 points in 66 games in his last underage season scores at a 282-point pace in his draft year? You tank — you tank as hard as you can. In the latter half of the 1983-84 season, the Pittsburgh Penguins and New Jersey Devils were in an unspoken, pitched battle for the bottom of the league and everybody knew it. While the Penguins would ultimately win out, sputtering to a 16-58-6 record (“good” for 38 points in the standings) to New Jersey’s 17-56-7 (41 points), the two teams were coming from distinctly different franchise backgrounds.

Using information from our new interactive charts, we can see what set these teams apart, and led them to take different paths in what turned out to be a pretty wild race to the cellar of the NHL.

The Art of Tanking: The Pittsburgh Penguins in 1983-84

While tanking is a hot topic in this year’s NHL, the act of tanking is as old as the idea of granting the worst teams a shot at the #1 pick in the draft. Case in-point: the 1983-84 Pittsburgh Penguins, routinely considered the most overt of tankers in NHL history. The graph above is just one example of their tank, and man is that bad. The yellow and grey lines indicate one standard deviation above and below league-average historical possession (using 2-Period Shot Percentage, or 2pS%, explained here). The blue line is a 20-game moving average (the orange is cumulative), and you’re seeing that right; a team close to the middle of the pack dropped nearly two standard deviations, or from near the top to near the bottom of the league. That graph, and all the ones below, are just some examples of the kind of tinkering you can do with our new interactive graphs, which I highly recommend you check out.
