Randy and Jake

Towards the end of the season, I thought it was commonly accepted that Randy Carlyle would bite the dust in the offseason, paving the way for this current Leafs core to get a chance to compete for a playoff spot under a different head coach. Perhaps one that isn't so deliberately harmful on the possession game.

A lot of people, when pointing out the flaws in any sort of stats-based analysis, like to mention that hockey is a very fluid game with lots of moving parts. It makes data recording more difficult. I wouldn't say that's necessarily true. If you've tracked zone entries, which involves recording which player moved the puck into the offensive zone and the way he did it, you begin to notice a lot of repetitive movements that have wildly different results.

Dump and chase, as a tactic, is only noticeably successful when a defenceman is forced into making a mistake. That's one that is rarely made by NHL defencemen anymore. Usually, a d-man who is first on the puck has the ability to move the puck away from a dangerous area, out into neutral ice, and we can repeat the cycle. On the occasions a forward chips and chases the puck past the defenceman, he's usually out-skated the other players on his team, and has no support even if he has the puck down low.

Entries into the zone with the puck, however, are not only pleasing on the eye (watch what Patrick Kane does in the neutral zone next Chicago game. You may develop an appreciation for what Kane does so well that a lot of players simply can't do) but according to some excellent research done by our pal Eric, lead to more shots. That post has been read by plenty of coaches at the junior and pro levels, and, being published in the summer of 2012, may be a precursor to a fundamental change in the way the game is played. There's a huge focus on possession.

Dumping the puck into the zone is conceding possession to your opponent. That may not have been the case twenty years ago, when new expansion franchises meant teams had to dress sub-standard defencemen, and players were not as well conditioned to receive body checks and hits as they are today. Carlyle loves his depth players to dump-and-chase, and the worst crime one of his players could commit is making a turnover. Carlyle will bench Jake Gardiner for one too many turnovers, but ignore the plays that lead to positive puck possession.

Justin Bourne over at the Score has an excellent post detailing why he thinks the dump-and-chase is coming to an end. One section caught my eye:

Watching my Dad play alumni hockey made me hate dumping the puck even more. The “old-timers” that played NHL hockey would play a bunch of 20-and-30-year-olds going 10,000 miles a minute, and they’d dominate them because they never willingly gave the puck away. If they encountered a wall of defensive players, they turned around, ran it back to their d-men (or even goalie), and started up again.

The dump-and-chase was introduced shortly after the introduction of the forward pass and worked wonders, exploiting the fact defencemen instinctively stood motionless at the centre line. We've been led to believe by people like Don Cherry and other dinosaurs with limited memories that this is the way hockey was played back in the 1960s and 1970s, by the successful teams.

Which makes the passage by Bourne interesting. Did Al Arbour coach his players the same way, and allow a younger Bob Bourne, Clark Gillies, Mike Bossy and Bryan Trottier to hold onto the puck and avoid giving up possession needlessly? There isn't too much footage available of full games from that time, but it's worth noting that our memories aren't flawless. Tyler at mc79hockey showed us a clip of the Philadelphia Flyers at the height of the 'Broad Street Bullies' era and the Flyers, unlike teams of today, avoided needless hits after players have given up the puck. They didn't play like the scary team some clubs, and players, modelled themselves after.

Also from that Bourne post is an interview from Kyle Dubas, the general manager of the Sault Ste. Marie Greyhounds:

"There’s nothing more that makes me or our staff cringe than when we’re watching players in Bantam or at the Minor Midget level and the parents are yelling and the coaches are yelling to get the puck off the glass or to dump it in and chase when they’re on the attack. I think for the most part we cringe because we know we’re probably going to have to correct those things to try to reset or rewire a player after a playing style like that was ingrained in them for 10 years, and it’s difficult.
I think every single player that plays the game, deep down and innately wants to have the puck on their stick. Myself and [coach] Sheldon [Keefe] told them that we weren’t going to be mad at our players if they tried to make a play and turned the puck over. That’s what every player in hockey wants to do, if they know that they have the grace of the staff."

Oh, to be able to write about a team whose coaches want players to have the puck and not give it up routinely.

The personification of the divide between Carlyle and a coach like Keefe would be Jake Gardiner. On the surface, Gardiner is a young defenceman who prefers to make risky decisions and plays to out-produce his mistakes. Essentially, he's high-risk and high-reward. In his post-season press conference, Carlyle didn't explicitly say who he was talking about during an anecdote about a particular young defenceman upset at how short his leash was, but it's not hard to divine the player is Gardiner:

"One example. One defenceman, a young defenceman, that's playing a rover type of hockey early in the season versus more of a condensed style of hockey and a more conservative style at the end of the season. And then coming back and saying that the leash he was afforded in the beginning of the season wasn't as long as he was afforded at the end of the season, and the coach says 'if you had played longer you would have had a longer leash' so it's like the chicken before the egg, but specifically that one player feeling that his leash was short where we believed it was longer than that."

I'm not sure Gardiner's talents are used to the best of their abilities under Carlyle. Once I get my hands on the All Three Zones data (donate here to the project. It'll improve hockey writing by leaps and bounds) I'll be able to suss this out with a little bit more data, but my feeling with regard to the Maple Leafs is that they were very restrictive in allowing their defencemen to move the puck out of the defensive zone, and restrictive about giving the defencemen much leeway in the neutral zone after a turnover. Entries under Carlyle can be characterized as possession entries by top six forwards, dump-in attempts by the bottom six forwards, and nothing in between.

The point is that Jake "Mistakes Happen" Gardiner will give up the puck more than a Tim Gleason, but he'll also have more opportunities to allow the Leafs to succeed. Hockey is not a game of raw numbers, but rather a game of ratios. You can't say "the defenceman that makes two mistakes leading to goals is worse than the defenceman that makes one mistake leading to a goal" even if you assumed the players had equal ice-time. I'd rather a defenceman who makes three plays and two mistakes than one who makes no plays and one mistake.

Humans, however, weigh losses higher than gains. It's a core component of Daniel Kahneman's Prospect Theory and, judging by the way some hockey writers tweet out giveaway numbers, some groups of humans are more susceptible to the inherent bias than others. The leaders in giveaways in the NHL: Erik Karlsson, Taylor Hall, Nik Hjalmarsson, Jeff Petry, Joe Thornton, Alex Goligoski, Phil Kessel, and so on, you'd be silly not to want any of those players on your team.

In the case of paying attention to Gardiner's errors and blatant mistakes (which are frequently discussed in this comments section) it's a case of missing the forest for the trees. When you step back and look at Jake's season as a whole, you see that every Leafs centreman is a better puck-possession player on the ice with Gardiner than without. Considerably, in fact:

leafs c gardiner WOWY 1

If possession isn't right for you, what about this? Every regular Leafs centreman, who all play different styles and have different usage, were on the ice for more goals for (per 20 minutes) with Gardiner than without, and on the ice for fewer goals against:

leafs c gardiner WOWY 2

(stats for both charts via Hockey Analysis)

Why would Jake be the target of so much consternation rather than a Gleason or a Paul Ranger? I can already hear people yammering that you don't need stats, you just need to watch the games, idiot, to know that Gardiner is the Leafs best defenceman. That's kind of the point, though. The Leafs have many problems, but Gardiner's game as a whole isn't exactly one of them. Regardless of the mistakes he makes on the ice, it's evident that the plays he does make (with or without the big leash) make the Leafs a better hockey club. Ultimately, that's what counts. In his press conference, Carlyle framed himself as the wise old sage and Gardiner as his talented, but foolish, protégé, but I'd argue that Gardiner's play is more consistent with the overall philosophy of successful hockey teams.

Carlyle's philosophy is bent on defensive mistakes, however. He wants to minimize his own and maximize the potential for an opponent to make a turnover, because that's how goals are scored. I'm sure I'll have the data to prove this at some point during the summer, but Carlyle preached an unnecessarily conservative system, and he has to go.

Great article. This quote reminded me of something:

"Why would Jake be the target of so much consternation rather than a Gleason or a Paul Ranger?"

I think Stan Bowman had an interview last week where he was talking about how coaches expect less out of bottom six fwds and bottom pair defensemen. Their jobs are a lot simpler and easier for a coach to look at and say "they did the job well" (i.e. they went out and hit someone, etc). This leads to a pro-[that player] bias. It's why guys like Ranger and Gleason (although Ranger was better later in the season) get free passes, while guys who have more dynamic skill sets (Gardiner, Kadri, Rielly) are given a harder time.

The main point being: Gardiner is great, but his game isn't "simple", so coaches who rely solely on their eyes may see him as a risk, and not understand how much better he makes the team.

If Jake Gardiner were on any team in the Western Conference, he'd already be considered a star.

"If they encountered a wall of defensive players, they turned around, ran it back to their d-men (or even goalie), and started up again."

So essentially what PK Subban does (and quite well at that)?

I tells ya man, that PK is the new NHL defenseman prototype.

I think this problem will sort itself out over time.

Part of the problem was that the Leafs didn't have a smart, mobile, defensive defenseman who would hang back. Gleason is too slow to be truly useful.

Petter Granberg is a defensive defenseman and he looked awfully good for his age in that final game when we finally got to see him. It was a crime that Carlyle was so reluctant to use the young guys from the Marlies. They should have given Granberg a look a month earlier. Next season will probably show Granberg was ready.

And we have another smart, mobile defensive defenseman in the system. Tom Nilsson was a 2014 Swedish Hockey League rookie of the year nominee. We should see him on the Marlies this next year.

Let Gardiner and Reilly play together on the powerplay, but give them each a responsible partner for some of the other minutes and the effects of the mistakes should decrease.

Imagine if the Ducks hadn't traded him, he would probably be one of our best defenseman after Fowler, Lindholm and Lovejoy

Cam -- terrific article; a great case study of the cultural gap in explaining different understandings of the game. Rations vs raw. Nice line.

One minor (technical) wrinkle on prospect theory and loss aversion. It basically reinforces your point. One of often forgotten points that Kahneman's makes is that it's not just a matter of "raw" losses vs gains (eg that people will prefer to avoid the former than gamble on the latter; that people value the same object more when they own it than when they don't). It's how people PERCEIVE the gap. The perception depends on how losses or gains are framed. These are called framing effects. Kahneman did a famous test in which he asked people if they would rather avoid a $5 surcharge or earn a $5 discount. The objective net effect is exactly the same. But how you word it (frame it) yields to different choices.

The key frame is whether something is tagged as a loss or as a gain. Turnovers are over-perceived because they are losses; possession is under-perceived as a gain.

Just a plug for why we need alternative frames for what's going on in hockey than just the "eyeball" view, much as we love to use our eyeballs when watching the game.

If anyone wants to read more on framing effects:

Kahneman, D. and Tversky, A. (1984). "Choices, Values, and Frames". American Psychologist 39 (4): 341–350

On Carlyle's own framing of things -- anyone who manages to garble metaphors of rovers, eggs, chickens, leashes in one passage should be suspect. Pardon the pedantry.

'if you had played longer you would have had a longer leash'

That's the money quote, to me, and tells you everything you need to know about Randy Carlyle's approach to developing young players; it's not his problem.

His "accountability" song and dance is just that, a song and dance routine designed to mask the fact that if you don't already have your NHL pension (400 games) Randy don't give a damn.

There is something that is is missing with these stats. Compare Gardiner TOI/game vs Gleason and Ranger and the rest of the leaf defence - what does that tell you of how Carlyle uses and thinks of Gardiner's game?

Yes Carlyle dogs Gardiner in the media but Carlyle plays him Gardiner big minutes (2nd to Phaneuf) even though mitten stringers like to have us think that Carlyle is benching Gardiner at every possible moment. When you reconcile that with your data you may conclude that Carlyle "values" Gardiner positive puck possession contribution more then Gleason. And Carlyle still would like Gardiner to improve his game because he has so much more potential then the lower ceilings of Gleason and Ranger.

Great article, as always.

I've always felt that Carlyle was likely referring to Franson in that season end interview. It seems to me Gardiner actually was on a longer leash by the end of the season. Not the case for Franson. Everyone else seems to think he meant Gardiner.

Anyway, I love your work. Thanks.
