Hell, we saw him creating chances for guys like Jordan Nolan and Seth Griffith. He gets the puck around to his teammates in good places. What we saw is corroborated by the numbers you posted - Sam's numbers aren't contingent on Eichel as a way of getting shots for his team. It's that it works really, really well when they are together for Eichel thus far in his career.
It would be so much more interesting if they would break Sam or Jack onto another line every now and then to make them look for others, to satisfy the desire to not see Sam defer to Jack so often and perhaps make a dangerous second line.
To @Jame 's point regarding Skinner or Eichel, both have positive impacts with Sam right? If they had four or say shockingly five offensively adept forwards where they could try to see what Skinner does with say Larsson as Nash/Ryan and Reinhart as something Skinner has not traditionally had on his opposite side while Jack gets Olofsson and some level of glue guy (Gus, Frolik, Asplund maybe, Kreider - dare to dream) to handle the grunt work that was falling to Sam when Olofsson was on that line. And just see if that works too. It's possible. They just need to sort out if the transition player to get the biscuit up the ice with Skinner is best Johansson or someone else. We know Skinner is able to generate goals (one way or the other) and that to maximize his benefits, having someone cover for him in the d-zone is best. Is that Reinhart? Is that Larsson? Is that Asplund? Heck, they were using Sobotka at that role and as a staff they were happy with it.
