Worst 20 Team Adjusted Corsi Ratings

I continue my summer sabermetrics and hockey posts today.  Today I will list the 20 worst players in 2010/11 ranked by team adjusted Corsi.  This is the counterpart to the top 20 players.  Players on this list are players that had poor puck possession at even strength.  In most cases this is because the player in question did not play very well, but in some cases on this list it is a player who played a tough defensive role.

This list is the difference between shots attempted (shots on goal, missed shots and blocked shots) for the player’s team and their opponents in 5 on 5 situations.  In order to compare between teams, we calculate a baseline for each team and subtract it from the raw rankings.

Here are the 20 worst players in 2010/11 by team adjusted Corsi rankings:

This list is limited to players who played on only one team in 2010/11 as it is unclear how to apply team adjustments in other cases.  This keeps Brent Sopel, Joffrey Lupul, Rotislav Klesla and possibly another player or two out of the running.  Both of these players likely would have been on this list otherwise.

For the large part, this list is a group of players who struggled in 2010/11.  I think the biggest counter-example to that statement is Manny Malhotra, who led the league with only 25% of his zone starts in the offensive zone.  He was a Selke Trophy candidate.  Adjusting for zone starts clearly show he did not have a poor year.  There are a few other players on this list who had a significant (though less than Malhotra) number of defensive zone starts including Zenon Konopka, Eric Nystrom and Vernon Fiddler.  I will look at a couple of the players on this list before adjusting for zone starts.

Brent Sopel played on two teams, Atlanta and Montreal.

Normally like the work you do here but I don’t like your premise this time.  In fact I reject the concept that you should be creating a baseline for a team. If every player plays alongside every other player then it would make sense.  I just don’t see that in real teams.

Take the Blackhawks.  The top line has Sharp/Toews/Kane on it, the checking line has Bickell/Bolland/Pisani.  None of the checking line players really ever play with any of the top line guys.

And Bolland’s line goes up against the other teams top line so it has the highest quality of competition.  In fact I believe Bolland has the Highest QoC for any forward and Bickell is in the top dozen or so. These two face an entirely different set of opponents then the Hawks top line.  What does the Hawks top line have to do with these players?

Bickell/Bolland/Pisani lose a little bit in corsi against their opponents.  They are supposed to since they have really poor zone start ratios and are playing against the best players in the league.  However, this line counterattacks well and is winning the +-/60 minutes battle.  They play the best in the worst situations and win.  Yet you have Bickell and Pisani as “struggling”

Why? because the Hawks top line is really really good in corsi and the Hawks checking line can’t compete with that?  Really?  Bickell’s production and value per salary cap cost is one of the best in the league.  Not the 20 worst in anything…

Right.  There are further factors that can be included to make things more useful.  Some of which I will add as I continue to develop things.

It’ll be interesting to see what Konopka’s performance looks like when more numbers are taken into account. He’s not exactly a world-beater, but he was pretty much thrown to the wolves taking tons of d-zone faceoff for a club whose transition game last year can best be described as “Is Grabner on the ice? No? *#&$%^!”
