This:
Also Orr's r-off has a lot of Don Awrey. Gretzky's has a lot of Messier and Anderson.
Needs to die.
Orr's R-off has a lot of every Bruins player. It may have
more Don Awrey than any other individual player, because he was a mid-high lineup defenseman (#2/3) who Orr apparently never played with at even strength, but this R-off is based on about 23 minutes of even strength time per game for the 631 games that Orr did play, and about 46 even strength minutes per game for the 74 games that he didn't. Factor in that there are about 4.8 skaters on the ice on average for one team at even strength, and we're talking about 86,000 man-minutes of ice time that make up Orr's off-ice comparables. Awrey played an estimated 8700 ES minutes as a Bruin, so if he never set foot on the ice at the same time as Orr (which I'm sure we can both logically rule out as possible and probably better quantify with minimal effort), he accounts for an absolute maximum of 10% of Orr's off ice data, but probably closer to 7 or 8%.
Similarly, Gretzky's R-off for his key seasons
has a lot of every Oilers player. it would be calculated as follows: (696 x 28 x 4.8) + (24 x 46 x 4.8) = 98841 ES man-minutes. Anderson and Messier during this time account for 17,343 minutes. We also know for a fact that they weren't completely, 100% separated from Gretzky. A simple analysis of their ES points over this time would show that. They were
usually separated from him, but not all the time. Anderson especially. So at most, these two players account for 18% of the play that made up Gretzky's R-off numbers, but the true answer is probably closer to 12 or 13%.
I also think it's a mistake to include Awrey as an example of a marginal player who pumps up Orr's figures because he was actually a very good player. Similarly, Anderson wasn't a
special player, certainly not the level of player one needs to point to as an example of why Gretzky's R-off would be so high. Messier, sure.
edit: just to explain further. I took a look at the 52 highest marks for total ESTOI in a season for Orr's Boston career (with Orr and his usual-but-not-always partner Dallas Smith excluded), and the players that turn up the most often are:
Esposito 8
Bucyk 6
Hodge 6
Awrey 6
Cashman 4
Green 3
Vadnais 3
Stanfield 3
those are all very good players, and none of them were with Orr all the time. Sometimes they were, sometimes they weren't. As a player who played half of the even strength time, it was inevitable he'd see some time with every line. Really, aside from Orr himself, the only major difference you can point to between the collection of man-minutes that make up his 61,000 on-ice minutes (of which 12,700 was him) is that his R-on
almost always included Dallas Smith, and it
almost never included Don Awrey, Carol Vadnais or Ted Green. Vadnais and Green are considered better players than Smith anyway, so while it was already clear that this wasn't a strong point, I'm now not really sure whether it's a point at all.
