I don't think it's correct to be sitting him, but the "4th on the team in points!" has been masking some pretty piss-poor offensive production that has been going on for awhile now.
Since December 1, Goldobin has three (3) primary points at ES. He is tied with Jay Beagle and Adam Gaudette. That's one goal and two primary assists, if you're wondering. In two months. There are 292 forwards in the NHL who have more. He's sat a few games but in the games he does play, he typically plays with Pettersson at ES and gets deployed in an offensive role.
The stuff about his defensive play and the moaning about him being scratched has really obfuscated the real story, which is that his production, his primary offensive production has been really, really, really bad. I don't think he deserves to sit over Granlund and Schaller, but typically when a guy is a pure offensive player whose production is buoyed almost entirely by PP play and secondary assists it's a red flag, and for some reason virtually everyone has blinders on about it because "GREEN HATES HIM CAUSE DEFENSE." Like, no, he's a purely offensive "scorer" who can't produce anything at ES.
Green, when asked about it, has made comments that he's basically unplayable when he's not being carried by Pettersson, and you can't play in the NHL if you're that dependent on one guy. I don't always agree with Green but he's right about that. Goldobin is 23 years old, has played 106 games and has shown almost no ability to put up good enough numbers when he's not playing with one of the best players in the game.
