Eklund has confirmed that the Islanders are willing to part ways with JG Pageau and Oliver Whalstrom to acquire Nylander but it is clear that they will need to add much more if they want Nylander. Most likely, the Isles will have to part with a top future asset such as a first-round pick, and probably more.
However, once a Nylander trade is completed, we can expect a Matthews contract extension announcement.
