I don't think you're understanding what I mean by Chunk Rate... either that or you're using the term "nearly" pretty loosely.
Souray had 53 points in 08-09, on 234 total Edmonton goals for. 53/234 = a chunk rate of 22.6%.
Campbell had 53 points in 2011-12, on 203 total Florida goals for. 53/203 = a chunk rate of 26.1%.
OEL's CR since the trade deadline is nearly double those guys, so I don't quite see the comparison??? You could've found many other players around the 20-30% range.
The point is, if Arizona scores a goal right now, it's basically a cointoss whether or not OEL gets a point. That seems pretty unusual, especially for a defenceman. It speaks just as much to Arizona's offensive ineptitude as it does to Ekman-Larsson's greatness, but either way, there's no denying he is hugely important to his team's offensive success right now.
I know I'm cherry-picking by looking only at stats since the trade deadline... the argument is that the Yandle trade helped OEL immensely by making him the undisputed top-dog of the desert dogs. I wasn't even aware of your comparison articles (though I'd take him over Muzzin in a heartbeat) - if anything I was suggesting that Dobber's article on the Yandle trade under-estimated the extent to which moving Yandle would help OEL.
