How Efficient is the NHL Goaltending Market?

Updated: July 4, 2012 at 4:30 pm by Hawerchuk



Imagine, if you will, a professional hockey league where every season, one of the league’s leading scorers came available as a free agent, looking for two-year contract at $2M per year, and could make your team 3-4 wins better.  Also imagine that every year, some of the league’s other leading scorers got locked up to long contracts and proceeded to turn in net negative seasons despite not being injured.  Unthinkable?  Well, this describes the NHL goaltending market!

The last three seasons, you could have had Mike Smith, Antti Niemi or Craig Anderson – all of whom had put up overall good numbers during prior their careers – for next-to-nothing and then reaped the rewards.  At the same time, you could have made the decision to go long with Ilya Bryzgalov or Marc-Andre Fleury and ended up with the same performance you could have had from a number of minor-league goaltenders.

Why does this occur? Relative to skaters, we just don’t get enough observations of goaltenders to figure out their true talent levels. But goalies are still evaluated on the basis of a year’s or season’s worth of data, just like forwards and defensemen, so their good (or bad) performance is over-valued.  And so we end up with big contracts for goalies with big error bars on their expected performance.

What I was wondering is whether teams have internalized these lessons in some way.  The percentage of total league salary going to goalies has dropped significantly over the last five seasons, suggesting some understanding of the potential inefficiency of goalie contracts:

Season Total $ Goalie $ Goalie %
2007-08 1404.8 134.2 9.56
2008-09 1615.7 140.1 8.67
2009-10 1648.3 143.3 8.70
2010-11 1704.7 144.8 8.49
2011-12 1776.3 145.7 8.20

But at the same time, teams continue to dole out huge long-term contracts to goaltenders, particularly their own goalies – all but one of the eleven five-plus-year contracts went to a team’s own goaltender.  So are the teams that spend a lot of money on goaltending spending any more or less efficiently than the teams that don’t?

  Save % GVT Salary above Repl $M/Win Wins
“Top 10” 916.2 163 59.1 2.18 27.1
“Bottom 10” 911.9 56 22.0 2.35 9.4

As far as I’m concerned, it’s a wash.  The more you spend – in general – the better your team’s save percentage.  (We expected that.)  But teams that spend more on goaltending are no more efficient than those that spend less.  Of course, just because a team spends less, it doesn’t mean that it’s better at allocating resources.  It’s better to look at the top-paid goaltenders and see how they performed relative to their contracts:

  Save % Above Repl Salary above Repl $M/Win Wins
“Top 16” 916.7 190 73.7 2.33 31.6
“Next 16” 913.1 59 16.2 1.64 9.8

Just so that we don’t get confused by RFA and ELC contracts, I looked at every goaltender age 28 and over who made $1M or more.  The top 16 goaltenders made, on average, $4.6M over replacement, while the next 16 made $1.0M.  (Interestingly, both groups had the same standard deviation on their save percentage, so it’s not as though spending more money gave them more certainty.)  The bottom 16 goalies also played an average of 35 full games compared to 55 for the top 16.


I think we’re finally at the answer here: there’s huge value available in the second tier of goaltenders, though teams have difficulty evaluating them as they do with all other goalies.  Given that uncertainty, it is almost certainly better to spend less money on goalies and to give them the shortest contracts possible; forwards and defensemen are much more likely to be sure things, and you’re better off paying for certainty.
