I'm not going to disparage Honka, but given he is a "potential" based player, not a "sure thing" who is currently producing at the NHL level as a young player, we already have one of those in DeAngelo.
Never hurts to have more, but after Sanguinetti, Del Zotto, Gilroy, John Moore, etc...well, you can see why I, as a NYR fan, would be hesitant to deal Zuccarello for such a player as the base return in a deal.
I'd want a top 10 1st, or "sure thing" special talent prospect in return. Especially with 2 playoff seasons left at a crazy good cap hit on Zuccy's contract.
