Sounds like a lot of cope from you guys. Rantenen is a top 10 producer and goal scorer in the entire league, typically bested only by the likes of Mackinnon, Draisaitl, mcdavid, and Kuch. Necas has obviously been a great producer in his own right this year but he’s not on Mikko’s level at all. Carolina was already a contender before this trade and now they have even more talent, in an area where historically in the playoffs they’ve been a bit underwhelming (offensive finish).
That being said, center depth was sacrificed in the trade and this isn’t a video game. Who knows what this does to their chemistry. History is littered with trade deadlines deals that look good on paper but don’t work out, and the bigger the transformation to the lineup the worse it usually turns out.
But I wouldn’t dismiss this as making only a “marginal” impact, one way or the other.
