Henrik Sedin and True Shooting Talent
On January 22nd, I wrote about how Henrik Sedin's early-season goal-scoring 'breakout' was illusory. How has he done since then?
| G | SH | SH% | |
| Career | 137 | 1036 | 13.2 |
| Since Jan 22 | 7 | 50 | 14.0 |
| Oct-Jan 22 | 21 | 99 | 21.2 |
Oddly enough, my mere mention of Henrik's likely regression to the mean caused him to do so.
In that same post, I asked readers to vote on how many goals Henrik was likely to score this season. Looking over the results - 347 votes - the mean estimate was around 34. Henrik has 28 goals with nine games to play - what are the odds that he reaches 34?
Based on his season and career numbers, the most likely thing that happens is that he takes between 13 and 19 shots and scores 2 goals, finishing the season with a career-high of 30. This would give him an 18% shooting percentage for the season.
If you were going to bet on Henrik Sedin's shooting percentage next season, would you take the over or the under on 18%? Note that in the original post, one of the commenters definitely took the over: "this whole discussion is meaningless...henrik will still end up with 35+ goals, so the discussion is also wrong...henrik is for real. there’s no way he regresses."
Anybody else?!

To fully name and shame
henrik is leading the league in points, not goals, so this whole discussion is meaningless. ignoring that, henrik will still end up with 35+ goals, so the discussion is also wrong. anze kopitar was overhyped, henrik is for real. there’s no way he regresses.

Personally, I’d take the under next year. His shot totals are remarkably consistent and his goal increase over the past three years has been a function of an increased shooting percentage. He’ll probably go back to around 20-24 goals.

What about Sydney Crosby?
I remember getting in an on-line argument somewhere at the end of last season, with someone insisting that Crosby would never score 50 because his shooting percentage was too low. I argued that he was too young and shooting percentage is too variable for his “true shooting talent” to be determined.
But that leads to another question: how well can “true shooting talent” be determined for anyone? NHL careers are fairly short – say 12-15 seasons – and that during that time there are a lot of confounding influences as players’ abilities wax from their rookie year and then wane to retirement: changes in powerplay time, ice time, linemate talent, etc. Shooting percentage itself has a very small range – no-one would argue that percentages above 18% or below 8% (for a regular forward) are sustainable, and it’s likely narrower than that.
Are we fooling ourselves into thinking that we can predict what a player’s shooting percentage will be, when it can very commonly change by 5 points from one year to the next within an overall range of only 10 points? Without doing a mathematical analysis, I just think the variability is too high.
I've been looking at the sky
Definitely under. His brother is the featured shooter, he had to slide into that role, and thus got a majority of the good scoring chances/scenarios early on. They are clicking back into the old pattern as we speak.

Gabe, yesterday I heard the TSN panel say that Sedin should be the frontrunner for the Hart, and it reminded me of this article:
Prescient, no? Especially this bit:
Prorated Daniel ends up, and this is at EV only:
EV Goals: 59
EV+/-: 40
Shots/-: +475
Fenwick +/-: +733
Corsi +/-: +772**
Now obviously it’s a small sample (six games) and the bounces be the bounces, so 59 goals at evens, shattering Gretzky’s mark, well that just isn’t realistic. But with his historic ability to finish at a high rate at evens, 50 EV goals (which would be second only to Wayne, surely, and in a lower scoring era) is really attainable. And with Luongo behind him, an EV+/- of +60 is realistic. That’s Bobby Orr/Wayne Gretzky country. And with any kind of PP year at all, he would be the runaway winner of the Hart trophy, with a closely contested battle for silver between Iginla, Ovechkin and Zetterberg.
And Vancouver fans would be arguing for recognition of Daniel’s place amongst the best to have ever played the game,
Obviously it’s Henrik who has been fully healthy and his game involves scoring more assists, but his +/- could easily end up in the 40s when all is said and done, and he’s definitely in the discussion from the Hart despite being the same player as ever.
Obviously nobody’s clamoring to trade Daniel but he’s not getting Hart consideration either but it’s not role that has torpedoed his chance, but injury.

Any discussion on Shooting Percentage needs to include, if only as an anecdote, Alex Tanguay. In his tenth season, he is posting a 11.1% rate, which has finally dragged his career total under 19%.
A career over which he has attempted 1068 shots for 202 goals. In almost 5 years, Ovechkin has 264 goals over 2122 shots.
Heh.
So, is Tanguay due for a rebound?
Probably. He’s only 31, so it’s not like his talent has fallen off a cliff. The problem is that Tanguay takes few shots, so the sample size is small. He’s only got 82 shots this year, less than a quarter of what Ovechkin has, and with an expected percentage of (say) 15%, that means an error of +/- 5% on your shooting percentage. But yes, assuming he still plays some 2nd unit power-play time as he does now, he should be back to 15%, but with a wide error range.
