Geno's line has always clicked when it had three things on it. Geno as the playmaker, Neal, Sykora or Feds as the shooter and Malone, Talbot or Kunitz as the puck retriever.
I think Boychuk could be a fine player. I don't think he's a good fit on that 2nd line. He has the same major problem that TK and Sullivan had. He is redundant. TK and Boychuk both play the scoring role Neal plays, except they aren't as good at it. Sullivan played the role Geno plays, except he wasn't as good at it. It makes sense that Sully did better with Dupuis and Staal and its certainly not because they are a better line. He got to be the playmaker to Dupuis puck retrieval and Staal's scoring.
Right now, Boychuk is getting a lot of scoring chances. He's good at that. But chances don't win games, goals do. I would rather Neal get 1 or 2 scoring chances a game than Boychuk get 3 or 4. That would create more goals for our team. But Boychuk does nothing to help create chances for Neal or Geno. He needs them to create chances for him. He doesn't win puck battles very well. He isn't a great playmaker. And he has trouble standing up to top line defenses.
And ya, I hear the "well Neal was like this when he first got here too!" argument. Neal was not able to play the role we brought him in to play until his second year with us. He was brought in to be a shooter and the number 2 guy on his line. Playing with Letestu and Kovy he was always the main focus of the opposing defense. He had to create his own offense. That's not his game. He is a perfect complimentary scorer to a great playmaking center. Boychuk is playing the role we brought him in to play; but in his defense I think we brought him in to play a role he is a bad fit for. I don't think he's a bad player, I think he's playing in the wrong spot.
With the current roster (and ignoring the bench,) I think I would try switching him with Dupuis. Dupuis is the 2nd best puck retriever on the team after Kunitz; so that would be a solid upgrade for Neal and Geno. It would give Boychuk a chance to be the scorer on a line where the other two guys are better suited to be playmaker (Sid) and puck retriever (Kunitz) instead of missing a role. I don't think its a long term solution to anything, but its a better short term solution. Long term, I think Boychuk is a 3rd liner. I think his only chance of being in the line-up come playoff time is if we move TK but still have Dupuis in the top 6 so Boychuk can slide back into TK's spot.
Please, don't call me a hater. This is all coming from someone who was happy with the Boychuk pickup. I still am. I think he makes it that much easier to trade TK. And honestly, there's no reason for us not to try this kind of a pickup. I was also a big supporter of Neal through his first stint here. But if he's going to stay on Geno and Neal's line, I would rather give Jeffrey another shot there. Though I still go back to what I said before the season started: I believe Cooke is the best player we have (outside of Kunitz and Dupuis) to fill the left wing spot with Geno and Neal.
tl;dr Boychuk is playing a role he is ill-suited for. Try him somewhere else in the line-up.
