ROR hasn't been on the team since Skinner came, pay attention please
Your chart has no dates listed on it all, and there's a section of 425 minutes played for Reinhart without Eichel or Skinner, and my question is does that include ROR or not?
Also, a simpler way to show that Reinhart can produce away from Eichel would be to separate the points Reinhart got from playing with Eichel to the points he generated away from him, but I don't think that would further your argument.
Thus far, all you've shown are advanced statistic that show that Reinhart has a better CF when he's not playing with Eichel (aka when Reinhart's not facing the toughest competition) but you've provided nothing concrete in the sense that Reinhart has generated points playing away from Eichel.
All in all, it takes a powerful reality distortion field to think that Reinhart has shown that he's anything more than a competent, albeit, complimentary, first-line winger. He's not a center. He's not a line driver. He can't be relied on to generate offense on his own regularly. You stick Reinhart on the third line with the kind of linemates Skinner's had and he'll produce points like Skinner. You stick Eichel with those same scrubs, and he'll produce more points than both of them combined because he can generate offense on his own.
I would pack Reinhart's bags myself if Calgary was crazy enough to offer Monahan for him.
