NHL Playoff Preview - Eastern Conference
On Monday, I looked at the playoff match-ups in the Western Conference, a group of teams that I've seen with my own two eyes a whole lot, but because of that, also a group of teams that I judge based somewhat on how I "feel" about them. The Eastern Conference is a whole different animal. I don't think I've seen any of these teams more than five or six times this season, and there's not a single one that I really can't stand (although any team that employs Matt Cooke gets the stink-eye). As such, my predictions for the Eastern Conference will rely more on statistics (if you can believe it), which is too bad because these series look to be, in general, quite a bit closer.
So just as with the Western Conference, the first thing I'll look at is each team's record and goal differential against the other fifteen teams that made the playoffs. The table below is for regulation time results only and is organized by Pythagorean Winning Percentage (PW% in the chart), which is based on goal differential:
What a mess. In the Western Conference, the teams that won the most games had the decency to have the best goal differentials too. This time? Not so much. Two of the best three teams by goal differential, are also two of the three worst teams by winning percentage, and two of the four worst teams by goal differential are the top two by winning percentage. The Rangers, in particular, confuse me. The club was able to blow strong opponents out of the water a few times this season (including 7-0 and 6-0 wins over their first-round opponent!), but that success in individual games did not translate into winning more than they lost.
Before going on to the individual series, I'll give a brief explanation of the data (which has been gleaned from Vic Ferrari's Time on Ice and Gabriel Dejardins' Behind the Net). Each series will get three tables. In the first table, we'll see how the two teams compare in terms of controlling possession at even strength, both overall and with the score tied. In the second table, we'll see how these teams have benefited from the percentages at even strength a the team level. In the third table, we'll look at the longer term goaltending trends for each team's starter (data from 2007-08 to the present, both regular season and playoffs), and look at each team's shot differential on the power play and on the penalty kill. All of this data is based on the full 82-game schedule, not just the games against other playoff teams. After the data, I'll talk a bit about each series and make a prediction.
(1) Washington Capitals v. (8) New York Rangers
Whenever you have a team with a sterling goal differential (the Rangers were +35) and a very good record in games decided by two or more goals (the Rangers were 18-12, fourth-best in the Eastern Conference), but a poor record overall, the big question is whether the team was unlucky in close games or being buoyed by a few strong performances. I don't think the answer to that question is always the same, but in this case, it looks to me like it's the latter. The Rangers have not been very good at controlling territory at even strength, but have had a strong PDO, to help prop them up. Despite getting shellacked by the Rangers a couple of times during the regular season, the Capitals look like the better team at even strength. Their power play is also the best in the Conference by shot differential, and significantly better than New York's. The big question for the Capitals is in goal. I have Michal Neuvirth starting even though I think Semyon Varlamov is probably the better goalie, but I'll bet that we see both play at some point during these playoffs. The Capitals are also dealing with significant injuries on the blueline (Tom Poti, Mike Green, and Dennis Wideman could all be out with Green being the most likely to return), but the emergence of John Carlson and Karl Alzner as a terrific tough minutes pairing will really help to stem those losses. I think the Capitals take this series in five.
(2) Philadelphia Flyers v. (7) Buffalo Sabres
Judging by the sizeable gap between the "when tied" numbers and the overall numbers, the Flyers look like they played with the lead an awful lot this season. The team also hasn't been very good since Christmas, which just so happens to be the part of the season that Chris Pronger missed big swaths of (he played in 15 of the team's 47 games). Their Corsi percentage since Christmas is just 48.1%, and with the score tied over just 49.0%. The Sabres, by contrast, had a terrible start to the season but have been flying since the Christmas break. Their overall Corsi percentage of 49.6% isn't all that impressive, but 52.6% with the score tied is pretty darn good. The Sabres also have a goaltender with a nice long track record of good results as compared to a raw rookie for Philadelphia. I do like Philadelphia's depth up front, and if Pronger was guaranteed to be healthy, I'd be picking the Flyers, but with Pronger's status up in the air, I'll go with Buffalo in seven games.
(3) Boston Bruins v. (6) Montreal Canadiens
Tim Thomas should win the Hart Trophy. To me, there ought not be any debate. The man set a new record for save percentage in a season, which isn't exactly an easy thing to do. He should win. Unfortunately for the Bruins, in every other category, they're just a little bit worse than the Canadiens. A little bit worse at evens, a little bit worse on the PP, a little bit worse on the PK. Still, the Bruins have the best player at every position (Thomas, Zdeno Chara, and Patrice Bergeron), and the forward group is filled with players who know what they're doing. Montreal's defense, on the other hand, just doesn't give me much confidence. "Old and Slow Plus Subban" seems like a fair description to me, and I just can't believe that that will be good enough. I'll take the Bruins to win in six games.
(4) Pittsburgh Penguins v. (5) Tampa Bay Lightning
The big question for me was whether or not this team is any good without Sidney Crosby and Evgeni Malkin. Guys like Chris Kunitz, Tyler Kennedy, and Jordan Staal are good players, but they've been complementary players for basically all of their time in Pittsburgh. In addition, Crosby and Malkin represent $17.4M in cap space, which is almost a third of the team's payroll, so you'd have to think that the Penguins would struggle without them. And yet, at least at even strength, this hasn't been the case. Since Malkin left the lineup for good on February 4th, the Penguins have a 54.4% Corsi percentage (both overall and with the score tied) in 29 games. The Penguins also have a very strong top four defense, which helps them to match against a Lightning squad that relies heavily on two lines to do most of its scoring. If the Penguins can match Staal's line against Steven Stamkos, which shouldn't be a problem at home, I like their chances. I'll take the Penguins in five.

Call me nostalgic, but I can’t count out a team with crazy old Roli between the pipes come playoff time. The only disagreement I have here is the TB/Pitt series. Take the lightning in 6, provided the old bastard doesn’t break. In fact, I can see TBay in the conference finals (not the SCF) if Roloson holds up.
I don’t understand how the Pens’ possession numbers can get better after losing Sid and Geno, while the Lightning’s have been coming down most of the season.

I’m with you Sheps. Those injuries make me nervous come playoff time.

More on Pronger from BSH. Yep, big difference maker there. Luckily, Philly’s top D can all log big minutes (like last year, must have been over 50 minutes per game combined for their top-4 being on ice).

Rangers
If I’m a Caps fan I might be a little concerned about maybe looking past the Rangers. That NY team is inconsistent, but they sure can get under your skin. Should they get feisty, and rattle the Caps early, they might make it respectable. And that PW% is a head scratcher in the East.

So by the stats Montreal is superior in every situtation of the game except goaltending but you take the Bruins because of a gut feeling about the lineups you admit to not watching very often. No offense, but that seems like some very wooly reasoning right there.

A few things here. Firstly, Montreal is only slightly better in most categories. If we assume that the teams generate 48 EV shots per game. So let’s give Montreal 51% of the shots, which is slightly worse than their rate during the season, but Boston’s also a decent team. Even if we go seven games, the difference is just eight shots, and if we use the long-term trends for the save percentage number, Boston is actually expected to outscore Montreal 11-10. The special teams stuff would look pretty similar. So yeah, the only thing Boston does significantly better is goaltending, but that’s a pretty big advantage!
And that’s if Montreal can play them even, which I actually don’t think they will. I really like Boston’s deadline acquisitions (Kaberle will help the blueline and Peverley is really good up front). I think Boston’s forward depth is very good, and that Montreal will struggle in the battle of the bottom sixers. On top of that, I think that Boston has the best individual players in the series (Chara and Bergeron).

Bruins-in-six seems to be everyone’s default pick, so I guess noone can really fault you for following the crowd.
That said, it’s notable, I think, that Boston had the highest 5-on-5 PDO in the league (1024, comining the best save % and 4th-best shooting percentage). Montreal had the second-worst 5-on-5 shooting percentage, which really hamstrung their offense, but managed to ride good goaltending to an almost-but-not-quite even PDO (995). (Incidentally, that means that the average goalie the Habs have faced has outplayed Carey Price.)
Everybody seems to think that the Bruins have the Habs crushed at evens, when the main difference between the two clubs was shooting luck.
I guess the big question is whether Boston can continue to ride the PDO gravy train and whether the Habs can shake whatever curse ails their shooters.
The series is a toss-up for me….I went with home ice.

I’m not so worried about the Bruins high PDO simply because I think Tim Thomas is, in fact, really good. If we just go by the track record for each goalie from 2007-08 until today, we would expect Boston to have a PDO of 101.0 in the series at even strength and 102.3 on special teams. I don’t think Montreal can make up for that difference with shot volume because their numbers aren’t that much better to begin with and because I think Boston’s additions at the deadline make them a better team than their overall record would suggest, which isn’t supported by their numbers since the deadline, but that’s a pretty small number of games.

Tim Thomas might be really good, but I personally don’t believe he is as good or better than Dominik Hasek. Some amount of his record-setting goaltending season has to chalked up to luck. YMMV, but I’m not ready to shoo him in the Hall of Fame as the greatest goalie of all time just yet.
That’s a little bit besides the point, though, because goaltending is only half of PDO and the other half might be more siginficant here. Boston was also quite lucky on the shooting side, whereas Montreal was very unlucky. That’s where most of the difference in results between the two club lies — and we know that while goaltending is a true talent (even if Thomas is not a .947 ESSv% talent), teams as a whole don’t have much in the way of true shooting talent.
Again — Boston had the highest ES PDO in the league at 102.4 The next closest was 101.9. Montreal’s shooting was so bad that despite strong goaltending they still ended up in the red at 99.5. Tim Thomas is a great goalie, fair enough, but do Boston also have unusually accurate shooters throughout their lineup?
As I said earlier, if we look just at the results from Price and Thomas from 2007-08 to the present and assume the shooters are average, we expect Boston to have a PDO of 101.0 in this series at evens and 102.3 on special teams. That doesn’t assume Thomas will perform at this year’s level, which I agree is unreasonable, but it does assume that Thomas is a better goalie by a fair bit, and I think that’s fair. Even if Montreal is better at generating shots (and I’m not convinced that they will be by very much if at all), I don’t think they can overcome that expected difference in the percentages. What would you say is the expected shot differential between these two teams?

The numbers I’m pulling out of my head are similar to yours. Score-tied puck possession probably in the vincinity of 51% to 51.5% in favor of Montreal. Boston is a slightly above average puck possession club, while Montreal is very strong (7th for Fenwick-tied on the year). Likewise, I think that if there is a gap in real goaltending talent, it’s going to be 0.005%, tops, and probably less than that. Perhaps I just don’t think as highly of Thomas as you do.
The thing is, you say Boston’s a stronger team than their record suggests because of their deadline acquisition. I think that, even allowing for literally historically good goaltending, Boston is weaker than their record because of shooting luck, and Montreal stronger. Both were really at opposite extremes on the shooting percentage spectrum. The Bruins’ acquisitions might make up for that, but still.
Not to say that Montreal will necessarily win. On such a short sample as a playoff series, of course the percentages are going to speak louder than the shot differential. So this series, like any closely matched series, is going to be more or less a toss-up. Like I said: it’s really all about whether the Habs can fix their shooting percentage and whether the Bruins keep making their shots.
To be clear, I don’t think Boston is better than their record suggests; I think Boston is a better possession team than their possession record suggests. We agree that the club’s shooting percentage is elevated and not likely to persist. I just think that there are other factors (goaltending, acquisitions, player history beyond this season) that will help push them into the role of favorite.

Funny thing about the Rangers, take away those two blowouts against the Caps you mentioned before, and their GD turns even. I think they are one team who is certainly propped up due to a few blowouts
Insert Witty Comment Here
Take out losses to Anaheim and 2x Philly and they go back to +9. Then take out the Philly win, and they’re back to +2. It’s a fun game.
Their record in games decided by 3+ is near the top in the league. (only behind VAN, BOS, CHI, PHI). It’s just they have a strange number of 5+ wins, with zero 5+ losses to balance it out.
They’re the only undefeated team in the league when leading after 2, but only had 29 such games, compared to 35-40 for most of the top seeds.
In the end though, they’re the epitome of crapshoot (shootout references not withstanding). Their best effort is really good, and their worst is really bad. I can see them as easily winning this series in 6 or 7 as I can see them get swept away.
