NHL 4th Round Draft Pick Probabilities and Expected Value

What is the expected value of a fourth round pick in the NHL draft (specifically picks 91 to 120)? Answers below.


ABOUT THE DATA

The 2016 NHL Draft Study is basically spreadsheet of nearly every NHL draft pick from 2004 - 2013 (goalies and players older than 21 on draft day not included), almost 2000 players total. The data includes production, games played at every level/age, and salary earned between age 18 and 25. The entire sample has only played in the NHL under a salary cap. Statistics from the 2015/16 season have yet to be added. For more information about the data, click here.

Age: In this study, age refers to how old the player is on Sept 15th of any given season, since that's the draft cut off. It means that the "18 year old season" is the season after the first year of draft eligibility regardless of what month the player was born.

Statistical Career Milestone Probabilities

Below are 3 charts to determine the probability that a player reaches any given career milestone for NHL GP, NHL PTS, and AHL GP by any given age. The chart at the bottom is for Expected GP and PTS.

Important Notes:

*It is intended as a cumulative probability, but because of the nature of this time-series analysis, doesn't always behave that way.

Analysis:

* There is not much difference between a 3rd and 4th round pick, except that higher picks are slightly more likely to get AHL roster spots.

Salary and Expected Value

The Salary and Expected Value charts below provide some interesting information. The 18 year season is not included in the expected value calculation because only a tiny proportion of the population of draft picks are ready to jump immediately to the NHL, and there is very little variation in the salaries of those that do.

Then there is the ability to determine what proportion of the sample is earning what salary at any given age.  $0 players are those who play zero regular season games in the AHL or NHL (some players with season long injuries still register a cap number, like E.Johnson). It's important to note that these are not career earnings below, but rather for that specific age.

Salary: Refers to NHL salary cap hit as listed at NHL Numbers.com, plus up to $50,000 per AHL season.

Expected Value
: This is the amount a player earned in salary minus the expected salary of a player drafted in that position, at each age.

Important Notes:

*Salary/Pro: This variable is calculated by total amount of salary divided by the number of players who have turned pro (AHL or NHL).

*The sum at the bottom of SALARY INFO chart, the salary from age 18 is not included.

Analysis:

*66% of 4th round draft picks won't earn a dollar of NHL or AHL money at age 25

Development Matrix

If you would like to see how a sample of draft picks advances through different leagues and skill levels, welcome to the Development Matrix (or more correctly, matrices). If a draft pick played at least 1 game at any level last year, where is he likely to go next year?

Important Notes:

* KHL = Russian Elite, EurMA  = Euro Mainland Elite (Czeck, Slovakia, Germany, Swiss), ScanA = Scandinavian Elite (Sweden and Finland), EurB = All of the 2nd tier European leagues, EurJr = All European junior leagues,  CHL = Canadian Major Junior, WJC = Under 20 World Junior Championship, Tier II = All North American amateur that doesn't ruin NCAA eligibility, USDP = United States Development Program

* Age 17 is the first year of NHL draft eligibility.

* Charts meant to be read left to right, not up and down.

* Do not sum the numbers in any direction. It is what percentage of the sample played at least 1 game at any level and many play at more than one level.

Analysis:

* The % of sample that played Tier II junior gets higher as the rounds get older. More teams willing to roll the dice on high risk talent in later rounds.
