How Much Do the Kings Miss Jack Johnson?

If you would only listen, you might just realize what you're missing. You're missing me.
- Jack Johnson, Bubble Toes


February 23rd, the L.A. Kings traded Jack Johnson and what turned out to be their 2012 first-round pick for Jeff Carter. While most of us in the analytical community thought it was a steal, some thought Johnson would be a lot to lose. Let's take a look at how things have changed since he left.

Defensemen WOWY

Johnson split his time pretty evenly between Matt Greene, Rob Scuderi and Willie Mitchell. Here are the on-ice Corsi rates and percentages for each of these defensemen with and without Johnson:

Corsi RateWith JJWithout JJ
Greene-0.59814.786
Scuderi-7.268.194
Mitchell-6.92710.883

Corsi %With JJWithout JJ
Greene49.7%57.2%
Scuderi46.7%53.9%
Mitchell46.9%54.8%

I was expecting an increase, but wow(ee)! Johnson's time being split evenly between those three guys makes this even more damning. The strong pattern with all three defensemen effectively eliminates other explanations like zone starts, playing with better forwards or his partner switching to Doughty. Jack Johnson was dragging his teammates down, pure and simple.

Before/After

Let's now look at how the centers and defensemen he didn't play as much with have fared before and after the trade.

Corsi RateBefore TradeAfter Trade
Doughty10.8657.925
Martinez21.69124.28
Voynov11.63817.567
---------------------------------------
Kopitar14.95724.063
Stoll6.71311.484
Richards-6.5248.789
None of Above7.5398.077

Some of these numbers, especially Richards's, have a lot to do with Jeff Carter's play and how he has impacted the team indirectly - by taking tougher minutes and just shifting around the forward slots. No matter what, it's pretty clear that the Kings are doing quite well without Jack Johnson, thank you very much.

Conclusion

Since the deadline, the Kings have been one of the best teams in the NHL. Some of the improvement is what Carter has brought to the table and part of it is everything clicking and everyone playing well. A big reason, perhaps the most important, for their success since the deadline is no longer icing Jack Johnson 23 minutes a game. The Kings miss Jack Johnson as a teenager misses his virginity.

With Or Without You: Patrick Sharp


            The usage of Patrick Sharp has been a hot topic in Hawkland for the better part of two years now.  Sharp was used primarily as the 2nd line Center during Chicago’s cup run, and placing him on the wing of Kane and Toews confused many Hawks fans last year, especially down the stretch, when David Bolland was injured.  Loading up the top line then meant that Michael Frolik or Tomas Kopecky would play Center alongside Marian Hossa.  Center depth is still somewhat a concern for the Hawks, and this same conversation about where to put Sharp in the line-up lingers on.  Our goal is to use possession numbers to identify whether loading things up by playing Sharp with Kane and Toews actually resulted in an appreciable difference in the team’s ability to drive the play. 



            The results show that Chicago’s pure possession numbers take a slight hit when Sharp plays with Kane and Toews compared with when somebody else plays with the pair.  Sharp – Toews – Kane were together for 427 Even Strength minutes last year.  When those three were on the ice, the Hawks’ Corsi/60 was 15.155 against a Quality of Competition of -0.734.  Kane and Toews as a pair played 930 minutes with any other teammate not named Patrick Sharp, their Corsi/60 and Corsi Quality of Competition were 19.4 and 0.458, respectively.   What makes the decision to load up even more questionable is the impact on Marian Hossa.  Mr. Hossa has played 618 even strength minutes with none of Kane, Toews, or Sharp.  The Hawks still had a positive Corsi in that sample, though it was much lower, coming in at a Corsi/60 of 4.7. 

Now that we’ve established that splitting the pair up makes the most sense, the question becomes how to split them up.  The two primary options are either:

·      Other – Toews – Hossa / Other – Sharp – Kane

OR

·      Other – Toews – Kane / Other – Sharp – Hossa


Toews was paired with Hossa and somebody not named Patrick Sharp or Patrick Kane for 259 EV minutes.  The pair did well for themselves, putting up a Corsi/60 of 13.7.  This is all the more impressive when realizing this pair was generally out against the opponent’s toughest competition.  The Quality of Competition rating was 1.76. In other words, Toews and Hossa took on tough competition and still dominated possession.  Sharp and Kane were also impressive, with a Corsi/60 of 20.8.  The pair generally faced weaker competition.

The other alternative is pairing Toews with Kane and then Sharp with Hossa.  Toews and Kane (and no Sharp/Hossa) put up a Corsi/60 of 19.4 in 929 EV minutes.  The pair faced tough competition, though it was not nearly as tough as the minutes that Toews and Hossa played.  Sharp and Hossa have been together for 570 minutes, putting up a Corsi/60 of 15.5.  It is interesting to note the drop in the quality of Marian Hossa’s opponents when he plays with Toews compared with Sharp.  The Quality of Competition rating of Toews – Hossa is 1.76 compared to -0.7 when the Slovak winger is paired with Sharp. 

            The numbers ultimately bear out that splitting up Sharp and Toews is the optimal solution given Chicago’s current line-up.  From there, decisions on personnel get a bit murky, though there are some important implications.  First, is that none of Sharp’s minutes at Center can be considered tough.  This is interesting, as the defensive reputations of his two potential right wingers are quite different, yet the quality of opposition has not impacted who plays the right side on Sharp’s line.  We do, however, see a big drop in the quality of opposition when we compare Toews’ minutes with Kane to Toews’ minutes with Hossa.  The captain faced tough minutes regardless, though the 0.458 quality of competition when playing with Kane was a relative cake walk compared to the quality of competition he faced when paired with Hossa. 

            My personal belief is that the Blackhawks should pair Sharp with Kane and Toews with Hossa.  We can see that any line that Sharp centers will generally get softer minutes; given this, why not load up in both directions?  A line based Toews and Hossa features two elite two-way forwards who have shown the ability to crush territorially despite playing absurdly tough minutes; Sharp and Kane would reap the benefits of the other pair’s tough minutes.  It is also important to note that a Sharp – Kane pairing is considerably better than a Sharp – Hossa pairing in terms of puck possession even though the quality of minutes are effectively the same.

            In the end, this, to quote The Wire’s Marlo Stanfield, ‘sounds like one of them good problems’.  As a team that likes to play with the puck (and does so better than everybody else), the Blackhawks have an embarrassment of riches in top end talent.  The only thing that can undermine that would be playing Patrick Sharp on the left wing.

Part I.V: The Aftermath... Jakub Voracek and Rick Nash WOWY Analysis

Chase asked me to do some number crunching on Voracek. To be honest, I found the results surprising. The numbers indicate that Voracek is highly underrated and was a great pickup. It appears that he, not Rick Nash, was Driving Play at even strength in Columbus.

Here is how Columbus did at even strength with both goalies in net with both Nash and Voracek on the ice, one of them on and neither of them:

2010-2011 ESCorsiTime (mins)Corsi/60OppCorsi
Both67690.25.8240.499
Nash only-6405.1-0.889-0.136
Voracek only71414.310.2830.399
Neither-112453.9-0.2690.214

It surprised me that in the 20 periods worth of ice time he was without Voracek, the guy with the sixth most shots taken in the league (including PP) was negative, albeit slightly. It's too small of a sample to take the exact numbers seriously, but it's interesting to note that when Voracek was off the ice not only was Nash a negative-Corsi player but Columbus actually did better without him than with him. Voracek, on the other hand, did quite well without Nash. He did so against tougher competition.

This pattern also held if you look only at situations where the score was tied:

2010-2011 tiedCorsiTimeCorsi/60OppCorsi
Both55256.912.8440.192
Nash-13155.3-5.0230.002
Voracek15140.56.4080.66
Neither-52946.9-3.2950.021

Let's expand the sample by throwing in 2009-2010, when they spent more time apart. Here's all 5-on-5 minutes:

2009-2011CorsiTime (mins)Corsi/60OppCorsi
Both59713.24.9630.528
Nash only-611507.2-2.4281.325
Voracek only651421.12.7440.773
Neither-2534184.4-3.6280.497

and when the score was tied:

2009-2011 TiedCorsiTime (mins)Corsi/60OppCorsi
Both55262.812.5590.265
Nash-20584-2.0551.439
Voracek34508.94.0090.646
Neither-1641585.8-6.2050.468

Nash had tougher competition in his time without Voracek than vice versa, but Voracek's numbers are far better. I'll write a lot more on quality of competition later and come up with something more precise, but according to my rough calculations it looks like Voracek was somewhere between 4 and 4.5 Corsi shots better per 60 when you take the tougher opposition into account. Maybe a little higher if you only look at tied-score minutes.

Before the flood of angry emails from Jackets' fans comes in, I'd like to point out that this is all for 5-on-5 play. It appears that Nash was carrying the water on the Power Play, maybe the fans yelling "SHOOT" for the entire damn power play are smarter than we think, and he also played about 19% of Columbus' PK time. In both cases, the Jackets had better Corsi numbers when he was on the ice than off.

Expect Voracek to play a big role for the Flyers at 5-on-5 this season.
