Now that I have added home and road stats to stats.hockeyanalysis.com I can take a look at how quality of competition differs when the team is at home vs when they are on the road. In theory because the home team has last change they should be able to dictate the match ups better and thus should be able to drive QoC a bit better. Let’s take a look at the top 10 defensemen in HARO QoC last season at home and on the road (defensemen with 400 5v5 home/road minutes were considered).
|Player Name||Home HARO QOC||Player Name||Road HARO QOC|
|GIRARDI, DAN||8.81||MCDONAGH, RYAN||6.73|
|MCDONAGH, RYAN||8.49||GORGES, JOSH||6.48|
|PHANEUF, DION||8.46||GIRARDI, DAN||6.03|
|GARRISON, JASON||8.27||SUBBAN, P.K.||5.95|
|GORGES, JOSH||8.25||PHANEUF, DION||5.94|
|GLEASON, TIM||8.21||GUNNARSSON, CARL||5.48|
|SUBBAN, P.K.||8.19||ALZNER, KARL||5.35|
|WEAVER, MIKE||7.92||STAIOS, STEVE||5.15|
|ALZNER, KARL||7.74||TIMONEN, KIMMO||4.95|
|REGEHR, ROBYN||7.72||WEAVER, MIKE||4.67|
There is definitely a lot of common names in each list but we do notice that the HARO QoC is greater at home than on the road for these defensemen. Next I took a look at the standard deviation of all the defensemen with 400 5v5 home/road minutes last season which should give us an indication of how much QoC varies from player to player.
The standard deviation is 34% higher at home than on the road which again confirms that variation in QoC are greater at home than on the road. All of this makes perfect sense but it is nice to see it backed up in actual numbers.
