I promise not to bore you with too much math here at ON. However, based on my early experience it looks as though math is regarded as a guide along with observation at Oilers Nation, so there's an opportunity to discuss some very useful tools that some very smart people have created or derived over the last few years.

Gabriel Desjardins is a brilliant writer and problem solver. His blog is here and his stats mountain is here. Gabriel (among others) gives bloggers and math fans a chance to explore the NHL universe: lines, zone starts, shots for and against, even-strength scoring per 60 minutes, shooting percentage, he has all kinds of reasonable measurements that tell us more than the boxcars. I encourage you to read Gabriel's stuff, he is a generous fellow with his time (if I had to pay a dollar for every visit he'd own my house). Beyond that, I won't mention him here a lot, save for giving Gabriel credit for the things he created or derived. It is only fair.

Desjardins supplies us with a rational NHL "production equivalency" for lower leagues. He projects those leagues into the NHL, and explains it here. It is an exceptional tool, and has been tracking very well since we started using it for Oiler picks and prospects.

By way of example, here are two season's worth of quality picks (2007 and 2008) and their NHLE. It is followed in brackets by their actual NHL numbers the following season:

• Patrick Kane, OHL: 26-36-62 (ACTUAL: 82gp, 21-51-72)
• Sam Gagner, OHL: 16-39-55 (ACTUAL: 79gp, 13-36-49)
• David Perron, QMJHL: 13-14-27 (ACTUAL: 62gp, 13-14-27)
• Steve Stamkos, OHL: 23-19-42 (ACTUAL: 23-23-46)
• Drew Doughty, OHL: 6-23-29 (ACTUAL: 6-21-27)
• Luke Schenn, WHL: 3-9-12 (ACTUAL: 2-10-12)
• Mikael Boedker, OHL: 12-17-29 (ACTUAL: 11-17-28)
• Josh Bailey, OHL: 11-24-35 (ACTUAL: 7-18-25)

Those are really good projections. Gabriel has arrived at a solid number in terms of letting air out of the tires, and so we can look to the future with some confidence. I'm using his CHL, AHL, SEL and other equivalencies below, if you'd like to read more I would refer you to both blog and stats mountain.

BUBBLING UNDER: NHLE'S for Oilers top level F prospects (per 82 GP)

1. R Jordan Eberle 22-24-46
2. L Taylor Hall 17-29-46
3. L Magnus Pääjärvi 16-22-38
4. L Linus Omark 20-15-35
5. C Chris Vande Velde 13-21-34
6. L Philippe Cornet 10-17-27
7. L Teemu Hartikainen 12-14-26
8. R Toni Rajala 11-15-26
9. C Robby Dee 13-12-25
10. C Ryan Martindale 8-16-24
11. C Milan Kytnar 8-14-22
12. C Anton Lander 9-12-21
13. L Liam Reddox 9-9-18
14. C Tyler Pitlick 9-8-17
15. L Curtis Hamilton 7-8-15
16. R Colin McDonald 6-5-11
17. C Ryan O'Marra 6-3-9
18. L Drew Czerwonka 2-4-6
19. R Cameron Abney 2-3-5
20. L Matt Glasser 2-3-5
21. L Matt Marquardt 1-4-5

This is an outstanding list, the Oilers best prospect list for forwards in a long, long time. Three top drawer offensive talents, followed by a long-in-the-tooth prospect (Omark) who can score and then an exceptional college face-off man with enough offensive skill to do well when he turns pro. Cornet and Rajala are in the "tweener" zone, as is Hartikainen but he brings enough things to his game that you can see him winning a job in a 2-way role (outside the top 6F). Martindale is also interesting, and the best defensive forward on the list (Lander) does pretty well by this metric. There are no less than 6 quality prospects on this list (Top 5 and Lander) and we haven't even looked at Pitlick (whose numbers suffered due to lack of playing time in the NCAA).

BUBBLING UNDER: NHLE'S for Oilers top level D prospects (per 82gp)

1. Jeff Petry 4-22-26
2. Taylor Chorney 5-10-15
3. Jeremie Blain 1-13-14
4. Brandon Davidson 0-14-14
5. Kyle Bigos 4-6-10
6. Alex Plante 2-5-7
7. Theo Peckham 0-6-6
8. Johan Motin 1-3-4
9. Troy Hesketh 1-3-4

Martin Marincin's number isn't here, he played in Slovakia U-20 this past season and there aren't a lot of comparable defensemen who jumped to the NHL the following season. We'll get a read on him (WHL) this season. Petry is the best offensive option, and considering his wide range of skills should be a player we see in the NHL sometime this season. My preference would be for Petry to play an entire AHL season (the lesson of Chorney) before making the grade, but if the Oilers encounter injury he should be in the mix for callup. Plante, Peckham and Motin are stay-at-home types as is reflected here.

Desjardins NHLE's are at the very least a marvelous toy. I believe they are more than that: a strong prediction about a player's offensive ability at the NHL level, and as such this is an extremely valuable measurement.

One final item. Gabriel's number tells us we have something special in Taylor Hall. Desjardins: Based on the performance of thousands of drafted players, we can predict how many points a player will score in the NHL when he’s 21-years-old. If he’s 17, four years later, we expect him to score at 72% of his junior rate. But if he’s 20, on average, he’ll retain just 26% of his scoring.

There is some number massaging required to account for age, but this would make (with help from spOILer, comment #87 in this comments section) Taylor Hall's 21-year old NHLE 82gp, 32-52-84. We don't know Hall's TOI number (that had a major impact on Rob Schremp's 19-year old OHL season), but it is clear that the kid is an exceptional offensive talent. Gabriel Desjardins NHLE's are a strong predictor of the future, and for Oilers fans it is an extremely exciting time.

edit: i don't see where you're getting the 0.54 number from, where is that on the site? i see the 0.5 number for an 18-to-22 year old //NHLer number, so 0.54 for 18-21 seems about right, but i can't actually find that number on the site anywhere.//

It is extrapolated from the curves. Desjardins curves are very accurate. the 17 year old curve shows at .72-.74 and the 18 year old shows at .49-.50. hall was 2 months short of 18 at the start of the season. Nov. birth.

The difference between the 12 month period is .72-.49=.23/12=.01916666 *2months =.0383333 .49=.03833333=.54 x1.86pts = 1.005 pts/gm

Crap 1.005 not 1.05 I have been making these simple mistakes latley.

1.005 X 82gm = 82.4 82 pts/season

I know you are looking at the 21 year point but full core development can be 21 to 22 year so i look to look at the 22 year point on the 17 and 18 curves. You can get expected performance thru each year of growth.

July 16 2010, 03:32PM

@spOIler

i'm not sure where you are getting your 0.43 number from... can you point out where it says this... all i can find is the 18-22 year old number of 0.5

... and the (likely more accurate) number of 0.54 that rickithebear has posted

July 16 2010, 03:45PM

spOIler: yeah, now that i look at it again, your 0.43 is more accurate than rickithebear's 0.54

#106 commanfan13

While 130 might be just a touch out of reach for Gagner next year, it feels to me like he might be ready for a breakthrough into the 70-point range.

All this type about the new kids - one of which is only a year younger than him, two of which don't have his draft pedigree, and all three of which never tore up junior the way he did - has to be motivating him.

Management might be kicking themselves soon if they don't lock him up for a while this summer.

#110 mike
July 16 2010, 04:03PM

"I was just wondering what the difference was"

I was just as lazy. But here goes. spOILer did two estimates for Hall @ 21 yrs in the NHL:

1.43ppg X .72 X 82g = 84 pts based on 08/09

1.86ppg X .43 X 82g = 66 pts based on 09/10

Seguin would be:

1.68 ppg X .72 X 82g = 99 pts based on 09/10

? X .43 X 82g = ? pts based on 10/11

But "December player projects to score 50% more points [over the career] in the NHL than the player born in January"

If you took that literally for 09/10:

Hall 66 pts + 25% = 82 Seguin 99 pts - 25% = 74

But if you interpolate the equivalencies by birth month, for 09/10 you get:

Hall 1.86ppg X .54 X 82g = 82 pts Seguin 1.68 ppg X .60 X 82g = 82 pts

So it looks like 82 pts is a good estimate for both for now.

I'm actually alright with projections. The only Desjardins stuff I was familiar with was the quick primer Willis provided when comparing Kane to Gagner and their respective transitions to the big show. I thought it was interesting then, and I think it's interesting now. It'll never be an exact science, but as Lowetide says, the Oil have something special in Taylor Hall. You can tell by watching him play (which satisfies the anti-stats brigade), and the fact that the stats support that is the icing on the cake.

I am 100% satisfied.

"There certainly have been an influx of nerds since Lowetide came over. I think this is the first time I've really felt lost while trying to read through comments."

Actually Lowetide's article is easy too follow. It's just the jotting on the back of napkins in the comments that is overwhelming.

Apologies.

But putting the numbers aside it is very interesting that January-March born players outnumber October-December born player 3:1 in Junior but only 2:1 in the NHL.

That's a lot of October to December prospects that do better than you'd expect. Without using numbers I'd just say there's a lot of January-March kids finally being exposed when everyone catches up on growth.

Yeah - that's what I was getting at. I understand his article.

Edit: Wait, no it wasn't. Back to the archives.

Re-Edit: Wait, yes it is! The picture is wrong! It used to be a line graph. Now the article doesn't actually describe the picture like it used to. It used to be a comparison chart between Gagner, Eberle, Kane, and Hemsky and how their production increased through junior and into their draft year. There may have been 1 more player but I can't remember off the top of my head.

#118 spOILer
July 16 2010, 04:20PM

Mike, Desjardins also mentions a 35% haircut in his article on the PPG basis:

An entire year’s worth of players become eligible for the draft, but the players born earlier in the year have a peak value 35% lower than players born late in the year.

That would give a bottom end of the range at 64 pts for Seguin.

#119 spOILer
July 16 2010, 04:26PM

If we were to pretend Seguin was born 32 days earlier, (Dec 31, 1991) his 21 yo projection would range 59-65 pts based on the same 2 equations I used above for Hall. Which seems to support Desjardins' Q1 haircut.

#120 mike
July 16 2010, 04:30PM

@ Lowetide

If anyone can crunch Desjardins' raw data it would be good to recalcuate the equivalencies by quarter. (somewhere else!)

This would make way more sense than using .43 and .72 for 2 prospects 2 months apart by age. Desjardins noted that an Nov. 18 yr. old (Hall 09/10) is going to out produce a Jan. 18 yr. old (Seguin 10/11) by 50% which means he really needs roughly the same equivalency factor as a Jan. 17 yr old (Seguin 09/10).

#121 mike
July 16 2010, 04:37PM

"If we were to pretend Seguin was born 32 days earlier, (Dec 31, 1991)"

But only if you pretend that was his 3rd OHL year. ;)

But your quick pretend does show that interpolating by quarter is probably better than Gabe's current method. In other words the data and all those missing Q4s and superfluous Q1s do suggest that exact age is more relevant to projecting than number of years in junior.
