Kunitz's issues aren't that he can't keep up with Sid. Hornqvist isn't fast either.
Kunitz just ****ing sucks, and should be happy with a 4th line spot. He shouldn't get one, because we have a multitude of players who have performed better than he has and make more sense to play over him, but if he HAD to dress, that's where I'd put him.
-edit- To clarify, I'd keep him as far away from our game-changers as possible. That means away from Sid/Hornqvist, keeping Hags/Kessel together, and I wouldn't saddle a rusty, just coming off of injury Geno with the corpse on skates that is Chris Kunitz. I also wouldn't give Kunitz a spot over Sundqvist, Cullen or Fehr--even though Fehr's been largely invisible. Better invisible than a huge detriment to whatever line you play on.
17 goals and 40 points says otherwise. 15 goals and 34 of those points were at ES. Hornqvist for example had 22 goals and 51 pts, however only 13 goals and 36 pts were at ES. Kessel who had 26 goals and 59 pts, only scored 22 goals and 42 pts at ES.
You can argue that Crosby props up those numbers - and to an extent he does. But we've been playing scrubs with Crosby for years who haven't produced anywhere close to what Kunitz has been able to do - and this year it was done without the benefit of cushy PP minutes/production to inflate them.
I'm I saying he's a top 6 winger? No. But he doesn't "suck". Do I want him gone? Absolutely. But that doesn't mean he doesn't have a place here or that he can't play the game in a middle 6 role. Because he can. He doesn't have the wheels any more, and his hands aren't quite as good as they were 5 years ago. But he's still decent defensively, will still lay the body, and more importantly, he's still fairly smart with the puck. He'll make smart little passes to get the puck to Crosby or Hornqvist in positions where they can do something with it. I would absolutely try him with Malkin to see if that works for either of them. As was noted, Malkin plays a slower game, and that should probably benefit Kunitz a little more.
Something that should be telling (and make people here happy) is that even Sully realises that he's not a top line winger. I mean even with 11 forwards, he still only saw 14/15 minutes of icetime. Which means that the coaches have recognized that while he's not useless and doesn't suck, that it's not in the teams benefit to be playing him 16-18 minutes like we used to see.
On a side note, I ****ing hate having to stand up and defend Kunitz. That's like defending Lovejoy. So please don't make me do it.
