He was productive before Marner got here.
You are buying production, especially on the powerplay.
But he wasn't as productive, not by much but not as productive. Looks like this year he will have maybe 37 goals, in that range. My point being, on a team without Mariner, Nylander, Mathews and his PP time will he be as productive? I'm not sure and I don't think he will have those totals if he is in Edm next year. If he wants to win a cup, continue the process he will sign here at a cap friendly number, if he wants the dough he may head to NJ, he would look good on the opposite side of Hall but I'm not buying all the hoopla that we have to sign him to a big contract and what a loss it will be. 37'ish goals is a lot but Kappy, Jonsson and a few others will get others and spread it around.
Now, if he backchecked like an animal Hossa was and still score all the goals then I would sign him to 6x7 or whatever that number is but defensively he is very suspect.
