I'm really puzzled by "journalistic integrity". What journalistic code of ethics is being violated by publishing an aggregation of several hockey writers' opinions here?
I can't agree there have been 4 greater defensemen than Bourque. But Shore might have been better. Both facts could be true....
4. Eddie Shore
5. Ray Bourque
In what universe?9. Paul Coffey
10. Chris Chelios
Do you se a pattern here? Ab-surd.27. Karlsson

48. Burns
The idea that +/- is a defensive stat comes from, of course, the idea that minuses are assigned for goals against. So really when someone says that +/- is a measure of defense what they really mean to say is that the minus is a defensive stat. Of course, there's a lot more to it than that, but at least if we get the pluses out of there we are eliminating a great deal of noise from +/-.
Orr had 526 adjusted ESGA scored against him in 657 games, for an average of 0.80 per game. Robinson had 1022 scored against him in 1384 games, for an average of 0.74 per game. If one is really trying to determine their defensive efficiency, that would be where you could start. Then you'd have to consider things like the quality of players on the ice with each of them. Robinson's teammates scored at a rate of 1.34 goals for, for every goal against during his entire career without him on the ice. Orr's teammates scored just 1.03 goals per goal against with him off the ice. Is that clear difference in teammate quality enough to account for a 7.5% difference in goals against per game? probably.
All those points are valid, not to mention ESGA really should be looked at on a per-minute (rather than per-game) basis. It's likely that Orr was getting a bit more ES ice time than Robinson (on top of way more on special teams) so his per-minute goal allowance rate would be even lower.

Question, is this the sheet in which Larry Robinson's EV+/- is 611? If it is, is there a way to sort the charts from largest to smallest?
Based on this assessment, the greatest defensive defenceman is Larry Robinson.
Robinson’s career Plus/Minus: Plus 722 over 20 seasons & 1384 games.
Orr’s career Plus/Minus: Plus 582 over 12 seasons & 657 games.
This 140 point differential, represents an increase in magnitude of 24% in efficiency over Orr. The magnitude of this differential increases significantly when taking into consideration that Robinson played 802 more games than Orr.
Imagine a conversation about who was greater offensively between Ron Franchis and Mario Lemieux, and someone saying not only Francis was greater because he had more points but he achieved to have more points while playing almost twice as many games.
plus/minus by game here is important, the fact that Robinson took almost twice has many game to get +24% in +/- is not increasing the magnitude of that difference, it is flattening it completely.
Now considering a bit latter you are writing:
Orr had 526 adjusted ESGA scored against him in 657 games, for an average of 0.80 per game. Robinson had 1022 scored against him in 1384 games, for an average of 0.74 per game. If one is really trying to determine their defensive efficiency, that would be where you could start.
You seem to completely agree already, so now I am just completely confused.
Yes, that's the one. and sorting is really easy, just use excel's native sort function, or click on the filter arrows at the tops of the columns.

We just shared mind about an obvious example to use to show that total +/- instead of +/- by game was a strange metric to use (I had yet to read your message when I wrote mine).If you're referring to the mention of Lemieux and Francis in this thread, that was me, though I wasn't arguing that Francis was greater. Quite the contrary, actually. I was pointing out that using raw plus/minus to rate defensemen, as the writer of the letter @seventieslord posted seemed to suggest would be something akin to saying that Francis was greater than Lemieux because of raw points.
It says that I need the password to sort the columns.
That's really strange, none of the versions I have ever seen have a password. Sometimes when you get a spreadsheet from a third party you have to click another button inside the sheet to confirm you want to unprotect it to make it editable. That might be what is happening?

In the most recent issue of THN, they added an additional 10 active defensemen (in alphabetical order) who although missing the cut this time, they feel could potentially make the list one day:
Mattias Ekholm
Oliver Ekman-Larsson
Dougie Hamilton
Torey Krug
Seth Jones
Ivan Provorov
Morgan Rielly
Jaccob Slavin
Marc-Edouard Vlasic
Zach Werenski
Charlie Huddy and Ken Daneyko did not make the list.
