NHL Entry Draft by the Numbers Part 4: Amateur League

It should be no surprise to anyone that Major Junior amateur leagues dominate the NHL Entry Draft but there are some other nuggets of information that might not be that obvious.

The below chart shows that OHL, WHL and QMJHL dominate the league compared to other leagues but when you look at the second chart in blue, it showcases a couple interesting stories: 1) The QMJHL under-performs compared to OHL and WHL. 2) On average, players drafted from the CCHA and WCHA do extremely well. (CCHA and WCHA have gone through some realignment over the last few years and can just be considered US Men’s Div 1 College Hockey)

Another spin on the data shows things a little better. For the chart below, I isolated the draft years to include 2001-2010 since players drafted after 2011 are still breaking into the NHL and eliminates a time bias. (i.e. only 10 players from the 2013 draft played in the NHL last year and including the 2013 draft would sku the numbers a bit.) 
Here is a list of the top WCHA and CCHA players drafted. Note there are several draft picks that have never seen NHL ice but that is consistent with a lot of players. 
….and for the heck of it since I had the data. Here is a scatter plot of number of players drafted and their games played in the NHL by CHL team. 
Let me know if you have any special requests.

NHL Entry Draft by the Numbers Part 3: Team Performance

Do you ever wonder how well your team drafts? Sure it is easy to call out a random draft pick that fanned out here and there but what about evaluating the performance over time? I’ve got you covered with my interactive team performance dashboard. This is intended to be simple and interactive so click and explore. Because of the different roles and responsibilities of certain players on a team, I again use Games Played as a way to evaluate success. I obviously have game stats data as well and might release a game stats version later.

If the dashboard doesn’t render…go here.

NHL Team Draft PerformanceDraft Years: 1998 - 2010              Game Stats: 1997 - 2014

I only use draft years up to 2010 but game stats of 2014. This was due to a lot of the players drafted after 2010 have not gotten a chance to play many years in the NHL and therefore would skew the stats. To keep it simple, goalies are excluded from the data set.

NHL Entry Draft by the Numbers Part 2: Expected Games Played

Yesterday I posted some data on the likelihood a player drafted in the NHL Entry Draft would eventually play in the NHL. Today I look at the average success by round. Measuring success is subjective especially when you consider the various roles and positions many players play on a team. To minimize the subjectivity, I chose to use “Games Played” (in the NHL) as a way to put everyone on even ground. (To simplify matters, goalies and goalie data are not included in any of my analysis.)

Since we are constantly dealing with rolling sets of data, I’ve created a line chart that breaks down the average number of games played for a player drafted by round by pro season number. I try to keep this stuff simple but if I am not explaining it well, please let me know.

The way to read this chart is that, on average, 1st rounders reach their peak in “Games Played” with 43.6 in their 6th year in the NHL. Keep in mind there are plenty of 1st rounders that might be out of the league or never played a game by year 6.

If you look over the entire career by draft round you get something like this:

The 6th round stands out as bucking the trend so maybe that it where you get find some sleepers in the draft. Here are some of some 6th rounders you might have heard of before: Matt Cooke, Chris Neil, Brian Campbell and a guy named Pavel Datsyuk. All of which have over 800 regular season games played as a 6th rounder. Cross referencing the 5th round, only Jaroslav Spacek has over 800 regular season games. Now Cooke, Neil, Campbell and Datsyuk will certainly have more games by the end of the year but there will also be players not included in my data set that won’t sniff the ice to pull the average down the other way.

Isolating just 1st round picks you start to see the top 5 picks substantially exceeding the other overall pick groups I created.

I called our Scott Gomez below to highlight a challenge with our data, particularly the +27 picks. With the expansion of the 90s, our late round picks are limited when it comes to 15+ years out.

Expect another post tonight digging into some other variables.

NHL Entry Draft by the Numbers Part 1: Probability Playing in the NHL

With the Stanley Cup Playoffs a distant memory, us hockey fanatics look to the NHL Entry Draft to fill the void. Like most professional sports amateur drafts, getting drafted gives players no guarantees on making the show. If you look across 10 year from 1999 to 2008, 56.5% of players drafted will never play a game in the NHL with about 25% of the kids drafted playing in over 100 games.

As expected, the earlier rounds have more success reaching the NHL than the later rounds. Here is a look at the same chart with looking at only the 1st three rounds of draft picks.

And completing the picture…isolating on the 1st round picks only.

Only the 2003 had 100% of their 1st Round Draft picks play in the NHL.

Tomorrow I post what to expect of the players by round.
