Predators vs. Sharks, Round One Preview

Our first playoff preview digs into the eagerly awaited #4 vs. #5 matchup in the West, between the Nashville Predators and San Jose Sharks. Last year, these two teams met in the first round and the Sharks dispatched the Preds in five games, largely attributed to two factors; the first being Nashville's inability to stay out the penalty box, and secondly, the advantage the Sharks had at the center position. Since that time, the Predators have upgraded significantly at the center spot (a couple guys named Arnott and Forsberg come to mind), and they've done a better job at staying on the positive side of the special-teams equation as well. Both teams have ranked among the NHL elite all season long, and are slotted 1st and 3rd in mc79hockey's Adjusted Goal Differential. But what does my analysis say about how these two teams match up?


For table explanation, scroll down to the bottom of this post.

How Nashville can score: The Predators' strength seems to be in perimeter scoring - their shooting percentage from outside of 10 feet is above average in all the different range slots, especially from 50+ feet, where they score almost twice as much as the rest of the league. The Sharks goaltending might well have a weakness there, as their save percentage in the 50-59 foot range is second-worst among playoff teams. That could translate into key goals for skilled Nashville blueliners like Shea Weber and Kimmo Timonen.



How San Jose can score: The vast majority (3.22 out of 3.74 total) of San Jose's goals are expected to come in the 10-29 foot range, where the perfect combination comes into play. The Sharks generate more shots there than average, they score at a higher than average rate, the Preds give up a relatively high number of those shots, and their goaltenders fare poorly in stopping them. The 10-19 and 20-29 foot ranges are the only ones in which Nashville's goaltending is subpar, yet those are exactly the ones in which San Jose is the strongest. That, to me, spells trouble for the Predators.

Summary: This picture is pretty ugly for Nashville - it says that on neutral ice, the Sharks would be expected to outscore the Predators 3.74 to 3.01. If we use Jeff Sagarin's rule of thumb, giving the home team in each game a credit of 0.25 Goals, San Jose still leads 3.74/3.26 for the games in Nashville, and dominates 3.99/3.01 at home.

Outside the Numbers: There are some factors that aren't reflected in these numbers that might play a role in this series. Nashville winger Martin Erat may well return for the playoff opener, and Scott Hartnell came back for the final two games of the regular season. If they (along with newly returned Scott Nichol) are able to play at or near 100%, perhaps that 0.73 goals per game differential gets reduced, but I highly doubt they're enough to swing the balance of power in Nashville's favor, even presuming all three are able to contribute effectively.

The Prediction: In all honesty, as much as I would love to see the Preds make a deep run in this postseason, this matchup doesn't look good for them. Based on what I'm seeing, everything would have to go right for Nashville to make this a coin flip, so I'm going with San Jose in 6 games.

Table Key:
Shots For = average of shots per game by that team, from the range specified.
Shots Factor = a factor representing how many shots the opposing defense yields in that range (1.24 = 24% more than average, 0.89 = 11% less than average).
Exp. Shots = "Shots For" times "Shots Factor", how many shots are expected to occur within each range.
Sht % = The fraction of shots from within that range result in goals.
Sht % Factor = a measure reflecting how the opposing goaltender handles shots from a given range (0.74 = 26% fewer goals than average, 1.53 = 53% more than average)
Exp. Sht % = "Sht %" times "Sht % Factor", the expected shooting percentage for this matchup.
Exp. Goals = "Exp. Shots" times "Exp. Sht %", the number of goals per game expected from each range.
Values indicative of significantly higher goal-scoring are shaded green, values for lower goal-scoring shaded pink.
All figures represent exponential moving averages, giving greater weight to recent performance. Empty-net goals and Penalty Shots are excluded.

How I'm Trying To Make Money Sports Blogging

To kick off this series of articles general sports-blogging articles here at OTF Classic, I think it's best to start with a comment that Brad left here last week, after I shared my goals for 2012, which include specific revenue targets:
I considered diving into the world of internet marketing myself, but I felt that my friends would hate me for bugging them about stuff. I mean, it's pretty low-risk high-reward, so it's tempting. I wouldn't mind reading about tips on how to maximize impact of blogging in general to make it a legitimate income source. Trying to make money at sports blogging can be a very touchy subject - for the vast majority of us, this is an activity we pursue to both exercise our creativity and share our love of the game, whether it's hockey, football, badminton, whatever, with fellow fans. Mixing that personal conversation with a commercial message can turn people off, especially if it becomes too intrusive for the reader.

Canadian Baloney, starring James Mirtle

A tireless refrain from the Canadian media is that Nashville is an absolute failure as a hockey market, and failing to move the team north of the border is an exercise in folly by the NHL.

Our latest exhibit comes from James Mirtle, usually one of the more thoughtful hockey bloggers extant:
But Nashville, quite simply, has proven it cannot sustain an NHL hockey team. Even with the lowest ticket prices in the entire league (I know: I've looked into flying there for a game or two) and a ridiculously forgiving arena lease, the team has had attendance issues despite having one of the best records in the league.

It's not a matter of Canadians not wanting teams in the southern U.S.; I've argued time and again in favour of teams like Dallas and Tampa Bay that have supported their teams and really brought something to the table in terms of bringing news fans and new energy to the game. That's a good thing.

The Predators, however, are not that, not in the beginning and certainly no…

Hooray for PythagenPuck

Back in November, around the quarter-mark of the NHL regular season, I wrote a piece looking at Expected Winning Percentages for each team, based on their Goals For/Goals Against ratio, using the PythagenPuck method as outlined in Alan Ryder's "Win Probabilities" article over at Hockey Analytics. Since we're approaching the end of the campaign, I thought it worth revisiting the two assertions I made back in November - that the Ottawa Senators were capable of getting back into the playoff race, and that the Boston Bruins were in danger of a freefall to the bottom of the standings.

Just to review, the basic idea behind win probability models like PythagenPuck is that over the course of a season, the Goals For and Goals Against numbers can be used to derive a team's winning percentage, within a a surprisingly narrow margin of error. For instance, if you only had GF/GA information, you could make a very good stab at projecting what the standings would look like. The w…
