2008 Draft - Forwards and NHL Equivalencies

After a short break over the weekend, I've put together the last NHLE article in this particular series with a look at how players from the 2008 draft have progressed. As usual, I'll be using the equivalencies developed by Gabriel Desjardins to give us some idea of where players stand in relation to one another when it comes to their offensive development. The Oilers have a couple of good prospects from this draft, but one really stands out. Or at least he would if it wasn't for the at-this-point-laughable inclusion of Steven Stamkos as a "prospect" - the distance between Stamkos and the rest of this draft class is completely bonkers. 

Star-divide

In the chart below, I've taken each player's goals, assists and points, converted them to a "per game" rate, multiplied them by the league equivalency number, and then expressed them as an "NHL equivalency" assuming an 82-game season. As you may have guessed, each league has a different equivalency number.  I've used this article for the translations from the KHL (multiply offense by 0.83), SEL (0.78), FNL (0.54), DEL (0.52), NLA (0.43), AHL (0.44), NCAA (0.41), WHL (0.30), OHL (0.30), and QMJHL (0.28); and this article for the translations from the USHL (0.27), MJAHL (0.14), and SJHL (0.13). At this point, most of the leagues have an NHL equivalency with the biggest exception being the ECHL.

Before I go ahead and put up the chart, a bit more explanation is needed. Not all of the players drafted in 2008 were actually the same age; in fact, several players had already passed through the draft at least once (and sometimes twice). All of these older players are included in the chart but are marked in yellow. Other players were first eligible in 2007 or 2008, but weren't actually drafted until 2009 or 2010. I've also included these players in the chart with "N/A" written in the "Draft Number" column, but if 2008 was their first year of eligibility, the yellow highlighting disappears. Further, the "Draft Number" column is not the player's actual draft position but the player's position among forwards. So, for example, Jordan Eberle was taken 22nd overall in 2008, but he was the 11th forward to be drafted, so his "Draft Number" in the chart is "11". The "Team" column is the team that drafted the player in 2008, not the team that has that player's rights today (Danick Paquette, for example, is still listed under Atlanta even though Atlanta doesn't exist anymore, and the player was just dumped on Washington). In addition, these numbers may be slightly different than the NHLE numbers you may have seen elsewhere for these players. That's because I include both regular season and playoff games in the results, which I think probably gives a better estimate of each player's real level of ability. Most of these teams aren't playing a balanced schedule anyway, so it seems to me that including the larger sample of games is the way to go. Finally, the "Rank" column is organized by NHLE. I broke the chart into five portions so that it would be easier to read, but it's still quite small.  You can click on a segment if you want to enlarge it.

This is always one of my favorite years to look at because the players are finally running out of places to hide. Sure, there are still a few prospects hiding out in the CHL or the NCAA, but for the most part, these guys are playing pro hockey, and it shows in their results. A year ago, there were thirty-two players from this draft class who had an NHL equivalency of 30.0 NHL points per 82 games or better. Now, there are just twenty-two. So what's gone wrong? Well, it seems to me that while the equivalency is very good at projecting the average performance of players who go directly from the CHL or NCAA to the NHL, that's not really the majority of players, and those that don't make it all the way there tend to struggle a lot more than the equivalency numbers imply. 

There were thirty-five players from the 2008 draft who played mostly in the CHL or NCAA in 2009-10 and then mostly in the AHL in 2010-11. If we use their NHL equivalancies from 2009-10 to create base-line expectations for 2010-11, which seems fair since these are young players that we expect to improve, thirty-four of these players fail to meet expectations:

Ahl_equivalency_medium

So, good for Luke Adam, but what the heck is going on here? The samples aren't huge, but these numbers aren't close to what we would expect if the AHL's NHL equivalency is really 0.44, the NCAA's is really 0.41, the OHL's and WHL's is really 0.30, and the QMJHL's is really 0.28. In fact, these numbers imply the following equivalencies for those leagues, assuming the AHL rate is correct:

More_nhl_equivalency_medium

That's a whole lot worse, folks! By tracking just those players who reach the NHL (i.e. the winners), it would seem that the equivalency numbers are providing a much rosier picture than is warranted for the (majority of) prospects who don't get to the NHL directly from these leagues. I'd want to do a more in depth study than this before tinkering with the numbers, but it seems to me that some tinkering might need to happen. The Philippe Cornet experience of point per game junior followed by a butt-kicking in the AHL is just too common.

On a more positive note, a lot of these players tend to get better as their AHL career progresses (hopefully toward the NHL). Guys like Andrei Loktionov and Zach Boychuk are near the top of the list this time after being in the middle of the pack last summer. I think a lot of that has to do with the fact that those two just finished their second AHL season, while many of the other prospects just finished their first. It takes guys time to adjust to the pro game, but a lot of these guys will get there eventually. This is particularly relevant for Oiler fans who are looking forward to players like Tyler Pitlick, Curtis Hamilton, and Ryan Martindale potentially turning pro a year before their peers. Don't be surprised to see those guys fall down the chart next year, only to have a resurgence the year after.

Of course, the guys who went straight to the NHL did very well for themselves. Jordan Eberle, Derek Stepan and Matt Calvert were three darn good rookies last season. I had been skeptical of Eberle before this season, but seeing him jump straight to the NHL and have success has really put my mind at ease. He's already a good player, folks, and looking over the rest of this draft class, that's something to be excited about.

it’s been a while since i’ve looked at the methodology behind NHLE, but isn’t NHLE non-transitive? that is, it assumes that players who come from junior will be ‘better’ than players who come from the AHL?

In this article Gabe is speaking about the AHL when he acknowledges that the method “tends to underestimate the difficulty of leagues that are substantially weaker than the NHL” and he also mentions that “the AHL league difficulty is higher for 18 and 19 year-olds than it is for players of all ages.” But most of these players were at least 20 years old in 2010-11, so I’m not sure how he would treat these guys, or whether or not a player’s rookie status would be considered relevant.

That’s the point I’ve tried to make on Lowetide’s site multiple times in the last few years. I’m glad to finally see another person notice the same thing. I roll my eyes every time I see NHLE being applied to some obscure teenaged prospect over at that site during discussions, which is a frequent occurrence, and a rather meaningless endeavour.

Doesn’t the NHLE presume that the player in question would be playing in the same role as he is on his current team? So wouldn’t that mean that for Phil Cornet’s NHLE to be accurate, he would still need to be getting 1C minutes with 1PP as well?

If that is in fact the case, it’s no wonder then numbers usually fall appart for many players and prospects – there aren’t a lot of players who play with St. Louis as a regular for the entire season. And those prospects RARELY ever spend any time in the AHL – whether it would help them or not.

No, it does not. It’s based on the average performance of players moving from one league to another. For example, on average, players who go directly from the OHL to the NHL retain 30% of their offense (and thus the OHL has an NHLE of 0.30), but we know that, on average, these players do not have the same role in the NHL as they did in the OHL. In fact, in most cases, these players have a smaller role in the NHL, and so a smaller role would be the assumption implicit in the numbers.

Gabe would later write that ‘we know there is no difference in the major junior leagues’ somewhere on the site, even though he clearly put the Q originally as lower. I think someone else did the work on that one. This kind of confirms the Q’s strength relative to the other leagues. They still produce less players, but they have less players in the league anyways (18 teams last year, 17 this year compared to 20 for the OHL and 22 for WHL). I’ve been using .30 for all the leagues, and have noticed this issue as well.

NHLE is a nice guide. But there are other factors than point production in making a NHL player obviously. We don’t like counting stats when judging NHL value, but we seem to freely use them for judging prospect value.

I believe I heard an EA Sports rep say on CBC radio that they used 58 (?) parameters on a player. Their playoff simulator was very good this year.

I think more data collection is needed to increase the accuracy of the stats at every level. By EA’s example the metrics would need to be very complex to narrow things down.
