As mentioned in the previous thread, JP is a decent twenty game stretch from having exponentially more value than Zacha currently does on the open market.
I can see why NJ would balk at the offer straight up, but the upside of Puljujarvi is still higher than that of Zacha, which is why I don't see the 'not even close' side of it.
Honestly, looking at NJ's needs and their depth beyond the draft, I personally think this deal (straight up) would be a decent gamble for them. The Oilers would be settling on a third line center.
