Tom Renney's Defensive Deployments

*Click to enlarge or find the full-sized chart here.

What you see in the chart above was first suggested by oilerBC in the comments of this article, namely adding a 3rd and fourth metric to advanced stats charts to tell a more significant story The horizontal axis shows qualcomp, specifically Corsi relative quality of competition taken from the venerable and terrifying Gabriel Desjardins' behindthenet.ca. The vertical axis shows percentage of percentage of faceoffs taken in the defensive zone, again from the venerable and terrifying one. The bubbles are color-coded: blue means the player in the bubble has a positive zonestart-adjusted Corsi, red a negative. Finally, the size of the bubble indicates absolute value zonestart-adjusted Corsi.

Tom Gilbert stands out in an enormous way here. Gilbert's adjusted Corsi is nearly zero, even while taking on the toughs. Corey Potter has a positive adjusted Corsi, he's playing against far easier opponents. Cam Barker is getting the easy opponents yet still has the worst adjusted Corsi amongst the defense.

Really cool stuff

I am going to try and replicate this for Ottawa’s defencemen.

You guys really are awesome. :)

Smid’s having an outstanding year so far.

What am I missing for Smid?

Your link shows him to have a +2.16 Rel QC Corsi, plus he has 49.7 Ozone start.

Why is his bubble red?

His zone-start adjusted Corsi is negative, and thus his bubble is red.

What’s the correction for ZS?

I assumed with less than 50% in Ozone it wouldn’t hurt it too much, not enough to make it a medium sized red bubble.

Gilbert Rel QC Corsi is 1.80 with a 48.3 ZS, but he is a minute red bubble.
Smid is 2.16 with a 49.7 ZS and is a medium bubble.

I’m curious.

My understanding is that it’s not “corrected” for Quality of Competition at all, so that 49.7 zone-start won’t give Smid much of a boost at all.

i’ve always had a soft pot for Smid, but now that things are starting to pay off for him i’ll continue saying what i’ve always said, which is that on a good team he is an excellent 2nd pairing defenseman, but not a top pairing guy.

he’s tough, can win puck battles and block shots, but more importantly he doesn’t do stupid things with the hockey puck once he’s got it.

problem is, he just isn’t an offensive threat in any way, and i think top pairing D need to have a component of that in their game.

Potter has that potential, i think. Gilbert’s already there, though there are still doubters to silence and probably always will be. Whitney, of course, is tops when he plays.

fortunately Smid doesn’t need to be that guy.

My goodness. Peckham, Barker and Petry line up like the first drops of blood on the bathroom floor when that time of the month arrives. But I just love the way Tom Gilbert is keeping nice and clean while the shit has been flying.

Very interesting and quite revealing

This is the best statistical representation of defensive performance I have seen. With your help Adnan posted the Sens version on Silver Seven Sens.
Thank you.

With all due respect the idea of an OZQoC chart comes from here:

Although I love the graphical representation of Corsi as a bubble instead of a label and would do the same if I had any skill with Excel graphs whatsoever.

Actually this looks more like Eric’s version, including the axis switch.
