Since you can see to the real heart of the matter, it should be easy to explain why his teammates perform better with him on the ice at even strength than without him, correct? Does he hand out Snickers to his wingers between shifts? People like candy.
More snark. Thanks again for proving my point about the Coots snobs.
In terms of "performing better"- there are only two metrics by which that comment can be supported, and neither of the two take into account Couturier's penchant for low percentage shots and shot attempts (which has become almost absurd this season - my favorite being a 3-on-2 a few games ago where he pulled up at the blue line and fired the puck up into the safety net). I would argue Corsi with him is particularly misleading for this reason.
He is a terrible, heavy-handed passer and rarely creates with the puck. The best you can say about him is that he is strong on the wall and a half decent finisher in tight, hence many of his goals - in fact I suspect all of them, besides the empty netters - are from inside ten feet, not that there's anything wrong with that.
My core position is this: he is not developing at all offensively, and in fact has regressed... and his intangibles aren't all people crack them up to be. His 5-on-5 defense, particularly against top-heavy teams, is good and would be of use in a playoff run. But game-to-game, he offers little in terms of special teams and nothing in the OT/shootout world (and yes, this does matter in today's NHL unfortunately).
But keep on dishing out that snark guys, makes for great conversation.
