See, there's a lot here I just don't agree with. What does he do for the PK that a dozen other players haven't? I'll agree he doesn't really play it poorly but he also doesn't move the needle in the other direction either. Guys like Comeau, Soderberg, Nieto, and Compher are at least a scoring threat when on the man-disadvantage.
Also, I don't agree AT ALL that he works hard every shift. He's not necessarily lazy but his physical game comes and goes and that's what I take issue with. He's pretty much useless unless he's throttling guys on the forecheck, and we only see that every 4th or 5th game or so. The rest of the time he plays rather pensively and is a clown show with the puck on his stick. He was a complete liability last game. I can see why Bednar doesn't want to roll out a 4th line of Kerfoot-Kamenev-Toninato but I think that line would be worlds more effective than watching the play die on Gork's stick every shift.
