He's a key part of the NHL's 28th-worst PK unit!
I'm okay with chiarot as our #7 next year. But we can't have him and Stu killing penalties. Hope morrissey, trouba, enstrom, Myers do more of that next year.

Chiarot was a defensive stalwart in 2015/16. No wonder the Jets penciled him into the top-6 for this season.
I thought this was interesting:
You can sift through the Tweets explaining the Star rating but it's basically what defensemen get sent out to face the best players on the opposition teams. Enstrom at 20. Postma dead last (and Chiarot not much ahead of him in the "Bottom 20") of about 200-ish players.

OK, seriously what does BPM mean, O or D?

So this is purely quantitative? bleh.
So basically it is a measure of coaches' confidence levels in the various players?
Yeah. Dellow explains it pretty well in that Twitter thread if you read through it. Maurice thinks highly of Enstrom - he's getting sent out there vs. the other teams' star players. And he thinks Postma and Chiarot need to be sheltered mightily.
Maurice tends to lean hard on his favoured players though - Top 3 lines get 90% of the ES ice time. Competent defensemen are out there for 25 minutes per game...so it might make things look a little more extreme. But Postma generally gets really low minutes as it is - and Maurice is sure trying to keep him away from other teams' top lines...so it's not surprising he's dead last.

As was hinted in the BPM write-up, the defensive version of the stat has basically zero value when compared to the information provided by XPM.
I'm convinced no matter who we have at the bottom, Pmo won't use them for 10-11 min, ever! That's his style.

DTMAH made two models: Boxscore Plus-Minus (BPM) and Expected Plus-Minus (XPM)
BPM looks at a player's boxscore statistics and places a value to them. For example: the even strength offensive values in boxscore stats weigh a player's goals, primary assists, secondary assists, unblocked shots, expected shooting percentage, and quality of teammate.
XPM is like a super Corsi. It adjusts for shot quality factors like expected goals but also adjusts for usage (all 9 other players on the ice for each event, coach of both teams, score of game, schedule (back-to-backs), and zone starts). The actual rate of events matters as well, and it will also heavily reward/penalize for good/bad shifts.
Putting an O or D in front of either model means you are only looking at the offensive side of things.
DTMAH combines these numbers to create his WAR.
EV Offense is a blend of OBPM and OXPM, while EV Defense is DXPM exclusively since the DBPM seems to cary no real value.
PP Offense is currently a blend of both OBPM and OXPM but weighted more heavily towards the former.
DTMAH then added some additional factors, with face-offs, penalties taken, and penalties drawn.
Thanks Garret.
Couldn't decipher the terms.
XPM in particular sounds interesting but WAR is still the top aggregate stat?
Coming up with a single stat that accurately describes a player's value has to be the 'holy grail' for analysts. When I see these new models being used I always have to wonder how well they are actually performing. We know Corsi has been demonstrated effective/predictive to a certain level because it has a history of performing. How well verified is WAR?
DTM's WAR is used combining XPM and OBPM in different ways depending on a few things:
1) whether even strength or special teams
2) whether forward or defender being evaluated
3) whether offense or defense

Box Plus-Minus (BPM) is a box score-based metric for evaluating a hockey player’s quality and contribution to the team. It is very different than an Expected Plus-Minus type model, which is a play-by-play regression metric. BPM relies on a player’s box score information to estimate a player’s performance relative to replacement level.
You should keep reading where defensive BPM isn't even used in the WAR model because it adds no value.
BPM only is used for offensive side of WAR in both EV and PP.
Through the use of ridge regression and Bayesian techniques, Expected Plus-Minus is a step forward into analyzing shot attempt numbers. While they do not allow us to isolate the cause of each player’s rating, whether that be through their teammates or competition, they do provide a more accurate representation of a player’s value than more commonly used methods.

What do you guys think about acquiring orlov as our 2 pair lhd?
My one issue with Schneider is his age. He's now 31 and is also signed to a very long term big money deal (He's worth every penny now). I think we need to ask does his age mean that he will still be an elite goalie through much of our window or are we buying him at the end of his peak and he declines through his mid 30s as we are contending.
I think he's a terrific goalie but trading our first this year for him is a bit risky due to his age. I'd just as soon grab another A prospect and look to FA or a younger guy like Ratna in a trade.
