Likely not, but never say never.
2 years ago the idea of trading Eichel at all would've been totally and completely absurd. You never know, they could find themselves underwhelmed with offers and some minor retention could lead to a far better return (akin to including JT Miller in the McD trade to get the best return (Hajek lmao) possible). GMs and Owners can be coaxed into things that would've previously seemed crazy. It's still very unlikely but you never know.
With no retention then I'm totally lowballing them. And don't forget, although his NMC hasn't kicked in yet, the Eichel camp will have some sort of input to where he goes due to the whole injury fiasco. It will be interesting to see how this shakes out.
