NHL man-games lost and CHIP analysis - 30-game report

This is my third look for the 2014/15 regular season at which teams have been hit hardest by injury/illness by trying to place a value on the games missed by players.

The concept again - multiply each game missed by a player by his 2014/15 cap charge (including bonuses), then take the aggregate of these figures for each team and divide by 82. This indicator of value lost to a team by injury/illness is called CHIP (Cap Hit of Injured Players).

This analysis covers every team up to its 30th game only. (Following from the 20-game analysis.)

For a more regular snapshot (i.e. weekly updates beyond the 10-game interval retrospectives), follow my critically acclaimed Twitter feed (@LW3H). CHIP rankings are also again being fed into Rob Vollman's Team Luck calculator on a weekly basis.

Alternatively...
Again, for a different indicator of player "value", I've also illustrated a similar metric based on TOI/G alongside the CHIP numbers.  Clearly, neither cap charge nor TOI/G are perfect measures of player value (whatever Anton Strawman might claim), since each have a number of limitations and inconsistencies, but they provide a decent comparison and the results do vary somewhat.

A quick summary of the alternative metric:

• TOI/G replaces cap charge as the measure of value in the calculation
• For goalies, TOI/G has been worked out as Total Minutes Played / Games Dressed For* - i.e. a goalie playing every minute of 75% of the games, zero in the rest, would end up with a TOI/G of 45 minutes (or close to it, once you factor in OT and so on).  [*Actually, "Games Played by Team - Games Missed by Goalie" - I'm not inclined to disentangle any three-goalie systems or minor-league conditioning stints.]
• This arguably overstates the worth of starting goalies somewhat, but it's simple and you could equally argue that a workhorse goalie is the hardest position to replace, so it's fair for them to have a much higher TOI/G figure
• Where a player hasn't played all year or where a player fairly clearly has a reduced TOI/G figure due to getting injured in their only game or one of very few games, I've used TOI/G from last season (or further back if necessary)
• For each player, multiply games missed by TOI/G to get (for a more palatable name) Cumulative Minutes of Injured Player (CMIP)
• Take the aggregate of CMIP for the team and divide by games played by the team to arrive at AMIP (Average Minutes of Injured Players) - it feels more understandable expressing this metric as an average per game (whereas CHIP is a running total)

The figures...
The table below shows:

• Total CHIP for each team over the first 30 games of the regular season, as well as the distribution of CHIP by position
• The player who has contributed most to the team's CHIP figure
• The number of players with a CHIP contribution of over $250,000 (think of it as being equivalent to a $1m player missing 20 games or a $4m player missing five games)
• AMIP for each team over the same period (e.g. an AMIP of 40:00 could be seen as the team missing two 20-minute per game players for every game this season)

CHIP figures in graphical form:

The same for AMIP (teams in the same order as the CHIP chart for ease of comparison):

The following is a ranking of teams by CHIP over Games 21-30 only, to further illustrate some of the biggest movers since last time:

10 second analysis...

• The Blue Jackets were actually slightly healthier in this 10-game stretch than they were in games 11-20, which isn't saying a whole lot
• The Canadiens were actually a lot less healthier in this 10-game stretch than they were in games 11-20, which also isn't saying a whole lot (with apologies to the Bournival household)
• A full time gig at the Denver Post for anyone who can name more than four of the 12 Avalanche players who missed time in the most recent 10-game period
• Anton Volchenkov's first puck bruise of the year means the Sharks are now the last team standing without a single injury on defense (Spoiler alert: this fact did not last much beyond game 30)

The next lists are the top 30 individual CHIP and CMIP contributions:

Where does it hurt?
This is another update of the crude injury-by-location analysis. Again, I’ve just used the descriptions found in the player profiles on tsn.ca, so the figures will encompass all the inaccuracies and vagueness within them. It should give a broad indication, if nothing else, though.

Despite the expertly handled mumpademic, illness absences still not a huge proportion of the total.

The crude rate of injuries (instances / total games played) remains at 0.88. This compares to 0.80 per game last year (0.80 in 2012/13, 0.78 in 2011/12 and 0.76 in 2010/11).

Finally, a first look for this year at the Evasiveness Index.  This is basically the proportion of injury instances for each team that have been described as either "Undisclosed" or the helpfully pointless "Upper/Lower Body" in the same TSN profiles.  I have made no judgement about whether the many instances of "Illness" (i.e. concussion) or "Flu" (i.e. concussion) other than those contracted directly from Corey Perry should also be included,

Despite repeated claims in the New York Post, the NHL and Coyotes ownership still assure everybody that they are not hiding anything.

Notes/Disclaimers

• Figures exclude a few minor-leaguers / marginal NHLers (usually an arbitrary judgement on my part) who had been on the NHL club’s IR since pre-season. Generally, if a minor-leaguer gets called up and then injured in an NHL game, his games missed will then count towards the CHIP though.  Minor-league conditioning stints immediately after/during a period on IR tend to be included in the man-games lost figures (but can't guarantee TSN's figures are always consistent on this)
• For the avoidance of doubt, suspensions and absences due to "personal reasons" are not included in the figures.  However, as per previous seasons, any "retired" player still under contract (Savard, Pronger, Ohlund) is still included. There are also one or two slightly less "retired" players not separately identified in the bar chart above (e.g. Souray, Timonen).
• There are undoubtedly a few inaccuracies and inconsistencies in there - I do the best I can with the information out there. Corrections might well be picked up in subsequent updates
• The cap figure obviously doesn't really correlate very well to the "worth" of a player in some cases, e.g. where players are seeing out an old (underpaid or rookie) contract or where players are horrendously overpaid and/or were signed by Paul Holmgren, Dave Nonis, Jay Feaster, Dave Nonis, Glen Sather, Dave Nonis...
• Also, for any player traded where cap hit is retained by his old team, the cap hit used will only reflect that for his current team
